who was aretha's opera coach for 20 years. lots of people might not associate her with opera but there was that extraordinary incident in 1998 at the grammys when she took over from pavarotti at the grammars —— grammys for nessor dorma with almost no notice? yes, the reason she was able to work with aretha franklin was that luciano pavarotti was having a party in new york city and asked ms franklin to learn the nessun dorma. she contacted me, i taught her the aria, andi she contacted me, i taught her the aria, and i thought that would be it. but because she was in new york and the grammy awards were one week after the party, pavarotti became ill and she stepped in with a few minutes of motors, no rehearsal, and she really just nailed minutes of motors, no rehearsal, and she reallyjust nailed it. she did an incrediblejob. she reallyjust nailed it. she did an incredible job. so

underrated. i know that eltonjohns said that he was —— she was one of his favourite pianists. and she was a meticulous arranger, apart from that voice. and i do know of people realise, but aretha franklin could sit down at the piano and play anything. she was extraordinarily musical, she had great instincts, and yes, she was particular about her arrangements. very particular. do you have a particular special memory? well, actually, it is about playing the piano. i was at a concert with her and i was in the dressing room and congolese rice —— condaleeza rice, an accomplished pianist, was playing a mozart concerto. we were talking and she suddenly became quiet and listened and said, i love that melody. she proceeded to sit down at the piano, listen, and played the mozart has

on our main story. let's stay with that top story and speak to our correspondent, chris buckler, in washington. all of this meticulously planned by senator mccain himself? yes, obviously he knew that he was suffering from this cancer that took his life and he spent a long time planning his own funeral services. what we have seen today is that in arizona he was involved in having sa ina arizona he was involved in having sa in a funeral that he wanted, in the state that he had represented for 35 yea rs state that he had represented for 35 years in congress. now his body is making a finaljourney to washington and it is a journey he made so many times during his life and he arrived at the base short time ago were again there was a ceremony, military

members standing by, as his widow and children arrived to be greeted by the defence secretary. a moment which is being looked upon in washington as a real opportunity to remember a man who was remembered fondly by both sides of politicians. he will get the honour of lying in state in the us capital. that has happened with only a dozen senators before. it gives you a sense of their high regard thatjohn mccain was respected in terms of the capitol building itself. you talk about both sides and the respect that he is held in. he made it plain that he is held in. he made it plain that he is held in. he made it plain that he wanted presented in this series of ceremonious comic is vision of the us. political rivals have been paying tribute but obviously no arrival of an invite to the current president or sarah

pailin. that will be made note of. he was someone pailin. that will be made note of. he was someone who pailin. that will be made note of. he was someone who did have enemies comic he advocated for a muscular —— foreign policy, really feeling like he wasn't a man on their side. there was the danger of thinking ofjohn mccain who represented everyone. that is not the case copy but when it comes to donald trump and his running mate sarah pailin, that idea of him not inviting them is going to be something that will perhaps overs ha d ow be something that will perhaps overshadow some events, particularly at the washington national cathedral, which will take place on saturday. if you listen to president trump, he has been someone has been very critical ofjohn mccain, he has questioned whether he should be regarded as a war hero. famously making those statements that a war hero is not someone who gets captured, as he was during the vietnam war. the president has been

careful with what he said and perhaps some of the events of this week in which we have seen the flag raised and lowered to half mast on a couple of occasions have not the sarah week showed the president in the best light. on the other hand we have had a comment from sarah pailin, talking aboutjohn mccain as being a maverick, a fighter and a friend. perhaps, although she wasn't invited, they will have fond memories of each other. scientists in london and texas say they've made a significant step towards an effective treatment for the fatal muscle—wasting disorder, duchenne muscular dystrophy. using a technique known as gene editing, the researchers were able to correct the dna of a small group of dogs with the condition. 0ur medical correspondent fergus walsh reports. part beagle, part king charles spaniel, these young dogs all have duchenne muscular dystrophy. the condition mostly affects males in both dogs and humans, and it gets progressively worse as they age. now look at the contrast with these females, who carry the faulty gene

but are unaffected. the dogs are part of a groundbreaking project published in the journal science involving the royal veterinary college and the university of texas. this research involved editing the dogs' genome, the recipe book for life. a faulty gene in the dna causes their disease, duchenne muscular dystrophy. the gene editing system known as crispr was injected into the dogs. it scans the genome, making a single cut at a precise point. this prompted a natural repair and enabled the dogs to produce the dystophin protein which is crucial for muscle strength. these dogs normally do not produce any dystophin protein or effectively no dystophin protein. and by modifying the dna in their muscle cells and their heart we have gone from effectively zero, to up to 92% levels of production, and that is widely predicted to be life—changing in human beings if we can get to that amount. you have to press that.

and that really could be life—changing for felix. he's six and his muscles are already beginning to weaken. early treatment is vital for him because time is running out. the prognosis for the duchenne kids is very, very bad. they deteriorate very quickly from the age of sort of seven and eight, and normally lose the ability to walk by the time they are 10, 11, 12. and then it's a very rapid decline from then. we trade in hope. so, you know, to hear about something like this is absolutely fantastic. these animals are all descended from one dog, whose owners brought it to the vet with the muscle wasting condition. and scientists found it had the same gene defect as in humans. these dogs are playing a key role in the search for an effective treatment for duchenne muscular dystrophy. a devastating illness. but longer term studies are needed

to show whether it actually improves muscle strength and is safe. only then would it be tested on humans. it is early days, but this research could ultimately benefit both humans and dogs, affected by one of the most severe of all genetic conditions. astronauts onboard the international space station are having to deal with a leak, most likely caused by a collision with a fragment from a meteorite. mission controllers were first alerted to the problem by air pressure sensors onboard the station. one of the astronauts, germany's alexander gerst, had to plug the hole temporarily with his finger, before it could be covered with sealant and tape. engineers on the ground are now working on a more durable repair, but they say the crew is in no real danger. now if you're a bit of an adrenaline junkie and you're based in london, there are all sorts of things you can do in and around the city,

including sliding down the 0rbit tower at the olympic park or walking across the top of the millienium dome. but you can now catch a ride in a killer whale. frankie mccamley has been finding out more. ata at a glance when you see the water break, you would be forgiven for thinking this is actually a real way all splashing in the tens. —— whale. look closely, it is a small submersible boat back and up to 60 mph and it is breaking waves in london. the whole boat goes underwater, you can feel the whole pressure. it also jumps out com pletely pressure. it also jumps out completely out of the water into the air. declares the air completely. anything away all does, this vote can do. so there was only one thing to do next, we gave it a go. —— a whale. —— boat. sorry for screening!

screams. we then dived down to go for the jump. screams. and my god! wholly moly. holy moley! but as chris the cameraman said we didn't get the shot, we had to go again. slightly dizzy, back on dry land as the next passenger arrived to ta ke land as the next passenger arrived to take out the craft, which was initially built for a bit of fun for the rich and famous. they were initially built for the superyacht industry as toys, four or five years ago they started get recreational licences around the world and we are the first one to bring them to the uk and europe. it is basedjust the first one to bring them to the uk and europe. it is based just next to the royal victoria docks and has

a lwa ys to the royal victoria docks and has always —— already taken out more than 1000 people. this is an area seeing more and more watersports, but this one is definitely the adrenalinejunkies. the but this one is definitely the adrenaline junkies. the team and we have one boat at the moment, but they are hoping to add a dolphin and a shark to the river soon. frankie mccamley with that report from the river thames in london. and finally, a baby mandrill has gone on show at the bronx zoo in new york. seen here with her mum sandy, the infant primate was born at the start ofjuly, the first mandrill to be born there in more than five years. they're one of the largest monkey species, but are classified as vulnerable, as their population is on the decline because of hunting and habitat loss. a name for the youngster has not yet been chosen. much more on all the news any time on the bbc website. thank you for watching. hello.

well, friday is not looking too bad at all across most of the uk. for the next couple of days will probably bring a little bit of cloud, a little bit of rain, not an awful lot. it is in fact going to be mostly dry for a lot of us and crucially, the temperatures will be rising. so while meteorological summer is coming to an end and friday is the last day of meteorological summer, and the 1st of september, it is autumn, technically, according to meteorologists. this is the forecast for the early hours of friday, a lot of clear weather out there, temperatures will be around 12 degrees at 5am on friday, a bit chilly in newcastle and edinburgh. we are talking about six, there will be a hint of autumn first thing on friday morning. some sunshine around and a beautiful start to the day. there is a weather front approaching, you can see thatjust to the west of our neighbourhood. that will encroach on to

northern ireland and maybe the isles of scilly later in the day, bringing a few spots of rain but nothing more than that. for most of us it is a dry day. i wouldn't rule out a shower in the south—east, so just a brief few spots of rain, that's pretty much it. temperatures will be typically around 20 degrees or so. friday is not a bad day. saturday, there is a weather front just stuck to the north—west of us. that means a little bit of cloud and rainfall. scotland, maybe the irish sea. we are not talking about an awful lot. if you squint you can see a little bit here just off lancashire and cumbria and south—western parts of scotland, maybe central parts of scotland, getting a few spots of light rain, possibly northern ireland. that's pretty much it. if anything, it will just be thicker cloud. central and eastern areas looking fine. if you've got plans on saturday, much of england is looking dry, and warming up as well, temperatures in the low 20s. saturday into sunday, we start to see warmer air coming out of france.

this is high pressure here, low pressure there. when we get this sort of setup, this kind of pattern, anything that comes from the west is going to get stuck, and then it sort of slides off to the north—west. so this is where we could see a little bit of rain during the course of sunday, but by the time we get to the afternoon i think the weather fronts will be stuck in the north—west, whereas many central, eastern and southern areas will remain dry. the winds will be light across the uk. that means those temperatures on saturday, or sunday rather, are going to be climbing. on sunday we could be talking about 25 degrees in the south—east. into the low 20s even further north. that's it from me. bye— bye. this is bbc news. the headlines: senatorjohn mccain's body has arrived at andrews air force base in maryland. the arrival came on what would have been his 82nd birthday. earlier, friends, family, and political leaders attended his funeral in his adopted state of arizona. he'll now lie in state at the us capitol before being laid to rest. there's been another anti—immigrant demonstration in the city
