everything. they seemed very, very happy. >> their conversation is the basis of the new bbc documentary, lennon's last weekend. for three hours and 22 minutes that december day, lennon went back through his life and career, remembering his early days in liverpool playing the local clubs before the beatles got big. >> they would be at the door. we would go to lunchtime and they would say, hey, john, will you sing? that's the kind of thing i missed, direct communication to the audience. >> reporter: he recalled his anxiousness about leaving the beatles. >> there's going to be a blank space in the future some time or another. that's when i really started considering life without the beatles. >> reporter: and he remembered his con to atroversial bed in 1

with yoko when they recorded "give peace a chance" at the height of the vietnam war. >> all we were saying was give peace a chance. just consider the idea of not having the war. just consider it. >> reporter: in 1971, lennon released his second solo album, "imagine." it became his signature song. but another track got a lot of attention. >> "how do you sleep." ♪ the only thing you done was yesterday ♪ >> i used my resentment against paul, a kind of sibling rivalry resentment from youth to create a song. >> does it go back that far? >> oh yeah, rivalry between two guys. it was always there. it was a creative rivalry. >> lennon also explained a wild period away from yo ko in the

early '70s. >> you two went through a bit of a break up. >> i call it my lost weekend. it lasted 18 months when the feminist side of me died a little bit and she said get the hell out. >> lennon said he hit the bottle like a teenager. >> i couldn't deal with the separation any other way. i just fell apart. the only thing i knew was go to the bar, drink. ♪ it'll be just like starting over ♪ >> reporter: by 1980, they had reconciled, and with "double fantasy" declared they were starting over. >> you look like two very happy people. >> reporter: but peebles had noticed a pair of armed body guards that accompanied john around new york. >> you could have parked two chevrolets on their shoulders. they were huge. >> reporter: that was how he ended his interview. >> one final question about your

private life and your security. >> i can go into a restaurant. you want to know how great that is? or go to the movies. people come up and ask for an autograph or say hi but they don't bug. >> reporter: when dinner was done zblsh d-- >> he said it's been an absolute blast. i said, yeah it has. and he walked away, got in the car. that was it. >> reporter: 48 hours later when peebles landed, his producer gave him the news. >> he turned to me with tears starting to pour down his face. i said, for god sake, paul, what's the matter? he said, john, he's been shot. >> reporter: peebles brought home the final radio interview. for the public they proved to be some of john lennon's last

covid test you can take at home. alison aubrey has that story. >> reporter: the town of bethlehem, pennsylvania, was famous for producing steel. but these smokestacks are relics, now a very different kind of industry is thriving in the lehigh valley. >> this company was actually founded in the shadows of the old bethlehem steel. >> reporter: this man is the ceo of the company that produces diagnostic tests you can do at home. as millions of americans lost their jobs last spring, he started hiring. and you've had to keep all of this open all through the pandemic. >> that's right, that's right. we've added more people too. >> reporter: they pioneered the first overthe counter hiv kit which gives a positive or negative to a user in just minutes. it's sold everywhere from walmart to cvs.

>> our experience in looking at pandemic, particularly hiv, around the world wrrks the only way to test people was to develop a self-test seemed to be ultimately the right answer for this pandemic. we can't have people circulating in public waiting to get tested. the best way to test people is to have the ability for anybody anywhere any time to test th themselves. >> reporter: the at-home hiv test was a small success for a small company based far away from the traditional centers of innovation. >> i know the company well. i raise my family well. this is an interesting part of the country where i think you get the best of being a midlantic population with a good dose of midwest values. >> reporter: and it's a good fit with his own values. >> having immigrant parents as scientists who taught me to love science and find ways to help people. >> and now tang and his company are trying to do for covid what

they did for hiv. amid long waiting times for covid-19 testing and ongoing supply shortages, the fda granted emergency use authorization for its self-collection devices in late october. >> and so we have products in the marketplace right now that allow you to sample yourself. this is a saliva collection tube. >> so, you just spit into that? >> you spit into this. send it in the mail safely. >> reporter: these kits still need to be mailed off to a lab, so they haven't yet solved the biggest challenge, the need for instant results. zb >> this is a very fast-moving virus. when someone gets infected with the clooronavirus, by the time they are symptomatic, they have probably already begun transmitting. >> reporter: assistant professor

of epidemiology at the harvard school of public health, as airports filled up over the holidays and cases and deaths continue to surge, he says the country would be safer if we had prioritized the kinds of tests that competitors are developing. >> if people are waiting more than just a few days to get their results, three days pretty much starts to make these tests almost useless for that individual. one day is already pushing it. >> reporter: the first covid-19 test that can be done completely at home was approved in november, but it's not yet available nationwide. and it requires a prescription. they now hope to have their test on the market by the first quarter of next year. >> so, you look at a test scrip, it has a control line. it has a test line. and within an hour, you know the result. so, no waiting in line, no waiting for labs, no waiting for the results to come back. you own the result yourself. >> reporter: tang knows that timing is key.

the company had hoped to have the test on the market by now. but as a scientist, he also knows the importance of getting it right. >> it's not an instant gratification approach you can take to develop a new product. the science takes time to happen. >> reporter: he showed us their hiv test, which is very similar to the covid test they've gopped. >> so, it means you can test yourself anywhere any time under any circumstance to get your result. >> you don't need to call your doctor and ask for them to write your a prescription. >> ultimately we're hoping this leads to people empowering themselves to find out more about themselves. >> what if your test is not 100% sensitive? what if it's something a little less than that? is it still helpful? >> the test will be helpful, and the reason is because you allow people to be tested more frequently. real time information, even if it's a little bit less precise, is more important than very

precise information that you get infrequently. >> the company is aiming for at least a 90% sensitivity rate for its over-the-counter tests. and he says rapid tests are key to prevents more deaths. even with vaccines on the way, it will likely be mid-summer before one is available to all americans. >> we don't know how easy or hard it's going to really be to get the vaccine out. we don't know how durable the immunity to this vaccine is going to be. we have to have contingency plans. and we have to have tools for right now. >> steven tang says the team at or ashore is geared up to give us the tools we need to keep ourselves safe right now and into the future. >> oh, boy, the people here have been working in these idea labs pretty much 24/7 for the last nine months. so, we're not insisting they work those long hours.

they're working those long hours because they're on a pursuit to really cha e the

tomorrow. they register young first-time voters, mostly college freshmen across the country. >> we've built our software, voter tracking, donor tracking. >> reporter: and they've connected with three dozen grass roots organizations. >> it just blew up. >> reporter: how many new voters did you register. >> we estimated 65,000. >> that number seems huge for me. does it seem huge to you? >> it's surreal. joe biden won this state by about 12,000 votes. and keep in mind -- >> younger voters coming into the electorate right now, too many are ideological liberal as compared to other age demographics. >> part of the group's pitch, good old fashioned peer pressure. >> how can you be okay with this? why wouldn't you want to use your voice to get out and vote. >> georgia is getting ready to

vote again january 5th in two senate run offs. students for tomorrow wants to register new voters like michael gusto. >> i've got to have some sort of input. i've got to know what's going on. >> valerie turned 18 last week. >> our voice will be hurt. >> you excited? >> i'm thrilled. >> but edward aguilar can't vote. he's still 17, but he's still using his voice. >> i can still have my own civic duty. i can still go out and get other people to vote. i can get people interested in politics. >> mark strassman in manslaughter yet at that, georgia. that's the overnight news for this tuesday. for some of you the news continues. for others check back later for cbs this morning. follow us online all the time at
