[ cheers and applause ] >> jimmy: palma violets, this is their album called "180," i want to thank selena gomez, i want to thank ben stein, apologies to matt damon, we ran out of time. thank you for joining us, "nightline" is next. ,,

tonight on "nightline." dream fulfilled? today as the president addresses the nation from the steps of the lincoln memorial. and two women who were here 50 years ago to share martin luther king jr.'s dream. it is what is painting the town red and purple and every color of the rainbow. it is the color run, and revolutionizing the way we run and stay fit. and there is something for everyone in our reunion

round-up. from insync to the vma's to a father and son, we guarantee you

from new york city, this is "nightline" with cynthia mcfadden. good evening, when martin luther king jr. stood up to address the nation on the steps of the lincoln memorial, his words did not use the phrase "i have a dream." he had used those words before, but they wanted something different. and then, mahalia jackson said "tell them about the dream." and he said the words that still resonate today. two young african american girls

went to the gathering, and had a message. today, they talk about what has changed and what has not. >> ♪ ♪ >> with songs and symbols from the struggle, a new generation of the faithful. >> and we thank the mighty god for giving us a martin luther king, we thank the mighty god who brought us a long way, from disgrace to amazing grace. >> the famous? >> he challenged us to see how we are all more alike than we are different. >> the powerful stood before the lincoln memorial. >> the march on washington teaches us that we are not trapped by the mistakes of history. that we are masters of our fate. but it also teaches us that the promise of this nation will only

be kept when we work together. >> the numbers were much smaller, an estimated 30,000 compared to the record quarter million who gathered 50 years ago for one of the most important speeches in american history. >> we can never be satisfied as long as our children are ripped of their self-hood and dignity, by signs that state "whites only". >> most politicians stayed away. not this time. >> martin luther king jr. urged his crowd not to drink from the cup of bitterness, but to reach across the racial divide because he said, we cannot walk alone. their destiny is tied up with our destiny, they freedom is bound to our freedom. >> and i think we all know how dr. king would have reacted to

have more than 835,000 african american men in prison, five times as many as when i left office. and with one third of all african american males being destined to be in prison in their lifetimes. >> reporter: the stories of ordinary people like sarah davidson and diane easell, raised in arkansas, welcomed as stars here. >> you were welcomed as negro girls, today you come back as? >> professional black women who have made a difference in america since 1963, made positive differences. she is a retired school teacher, i have done research. >> i came here as a young girl, never leaving arkansas before, being exposed to this city and the monuments here. and it moved me up. it took away some of the feelings i felt because dr.

martin luther king jr. told us to think positive and to go home and help our families and help our communities. and we did that. >> reporter: in 1963, they rode a bus from arkansas, this time, many of their children and grandchildren and families made that trip. >> all of those who sacrificed their lives, made it for us today. it seems to be slipping away from us, we need to recapture it. >> coming from all walks of life. it represents us. >> i would say if you can't take a bus ride for justice, then you know, you don't deserve it. >> right. >> so i'll ride that three or four times if i have to. >> exactly. >> thank you for this trip. >> reporter: the bus broke down on the way, but nothing could break their resolve to get here. sarah and diana were waiting to welcome them. >> you said you would get here.

>> sure did, sure did. thank you. yeah. >> reporter: emotionally, where are you today compared to 50 years ago in. >> emotionally, 50 years ago i was sad and angry. sad because living in arkansas, and being treated as a second class citizen was not a very good feeling. i was angry when i came here, and emotionally, when i heard dr. king's speech, i left with a different type of feeling because he had a dream and a vision. >> reporter: 50 years ago as tenth graders, they endured far worse than a bad bus ride. they survived the worst of segregation. >> my first interest came at ten years old, when i saw the little rock knights. i went there and there were national guards walking all around the streets. and it was scary and very upsetting for a 10-year-old. and i just began to notice

things and look at the color bathroom and the white bathroom. having to travel on a gray hound bus. >> reporter: feel people know that feeling better than john louis, a share cropper's son from alabama, who suffered beatings and arrests, and as he put puts it, stood in segregation's way. at the '63 march, he spoke with fire. today, he spoke with context. >> 50 years later, we can ride anywhere we want to ride. we can stay where we want to stay. those signs that said whites and coloreds are gone. the scars and stains of racism still remain deeply imbedded in american society. will it be stop-and-frisk in new

york, and the trayvon martin case? the mass incarceration of millions of americans, immigrants hiding in fear of the shadows of our society, unemployment, homelessness, poverty, hunger, or the new struggle for voting rights. each one of us today we must never, ever give up. we must never ever give in. we must keep the faith and keep our eyes on the prize. >> reporter: in 1961, louis was 23, king, 34. you were still a kid? >> i grew up -- when you have been sitting on a lunch counter stool and somebody walks up and spits on you? pour hot water and hot coffee on you, and you say you are committed to non-violence, you have to grow up. in 1961, the same year that president obama was born and to be beaten? you had to grow up. so by the time of the march on

washington, i was 23, but i was an older person. >> reporter: an old soul, as they say? >> i was an old soul. >> reporter: wednesday in washington, the old soul stood with the young. the words of dr. king as relevant now as they were 50 years ago. >> we have come to this hallowed spot, to remind america of the fierce urgency of now. now is the time. to make real the promises of democracy. >> we may not face the same dangers of 1963, but the fierce fear remains. we m the same flame that lit the heart of all who are willing to take a first step for justice, i know that flame remains. >> reporter: for two friends from arkansas, much has changed

in america since 1963. like the country they love. a little grayer, perhaps wiser and still moving towards the dream. for "nightline," i'm byron pitts in washington. >> indeed. our thanks to byron pitts for that. next, what is blue and painted all over? >> abc news "nightline," brought to you by macy's

. how would you feel about

running a 5 k race on a very hot summer day, having stuff thrown at you from all directions? oh, and paying for the privilege. if you don't think that sounds like a lot of fun get ready for a colorful surprise. it is steamy, sweaty and the hottest party around. >> reporter: at the beginning of every race, there are two possible outcomes. victory? or crushing defeat. and on this sweltering summer day, i have a lot of competition. 5,000 athletes, ready to give it their all. people like megan schutz, who we're about to find out has a lot to prove. so before i even get properly limbered up, the count down begins. >> three, two, one! >> reporter: and we're off, but i'm not nervous, because fortunately today there is a

third possible outcome in this case, getting tie dyed beyond recognition. this is the brooklyn color run. five kilometers of untimed revelry, where the 5,000 participants get doused with articles, not in the name of victory but with sheer joy. with entry fees of around $50 they're literally paying for the privilege to get doused. >> i just thought what would happen if you covered them in colors and had a party afterwards? >> reporter: and party, they did. the founder and master of ceremonies said he just had a hunch. >> i think people need a break, not to worry about the clock or

the guy next to them. >> reporter: that hunch was right on point. the business registered 600,000 runners at nearly 50 events in 49 cities last year. this year, there will be a million participants, that is tens of millions of dollars. plus, there are sponsors like chevrolet lining up for a piece of the action. the color run is leading the pack of so-called fun runs, although some think anything but fun including the spartan race, where the runners jump over fire, or the mud race, or where they battle obstacles, or the zombie run where you're chased by the running dead. there are now more than 30,000

5ks to choose from in the u.s. and the unexpected gold mine of publicity, with the runners desperate for the profile picture. the companies are milking it for all it is worth, encouraging the instagram to fire away. >> the images of the color run are very powerful. it made it grow very quickly. >> reporter: in fact, the color run is so popular, they bought out the entire country of white t-shirts. >> this happened in the middle of our explosion. and they said there is no more white t-shirts in the united states right now for you to order. >> reporter: schneider says fun and accessability is the winning color. >> it does amazing things for recruiting, for people to come and participate in an athletic event that they normally wouldn't. they would be too intimidated.

>> reporter: 60% of them are 5k runners, and then there are others like my friend megan, who is celebrating her overcoming heart surgery. she was operated on immediately. now after months of therapy, she is determined to fulfill her goal of running a 5k. but will she have the stamina? we may not set records, but we're getting it done and finally we cross the finish line. megan may be tired, but she is on top of the world. >> even though i can't wear short dresses because of my scar, i can run these 5ks. >> reporter: and it is pretty clear these people feel the same

way. >> next, could there be a reunion in store for this be loved band? did you know that as we age our need for protein increases, yet many of us don't meet our daily protein needs? that's why there's boost® high protein nutritional drink. each delicious serving provides fifteen grams of protein to help maintain muscle and help meet expert recommended daily protein needs. plus it provides twenty-six essential vitamins and minerals and is gluten-free. help get the nutrition you need with a complete and balanced nutritional drink. try boost® high protein. also available in powder. this has been medifacts for boost®. one may measure it by the thickness of its glass. the integrity of its high-strength frame. the amount of stitching in its interior.

real big deals this week and every week. in tonight's "feed frenzy," we noticed touching reunions of all kinds. one video making the rounds shows an intensely personal

moment, and heartwarming news, in of all places, syria. a young father believed his toddler son had died from the recent attacks until those close to him helped to reunite him with his little boy. we dare you not to cry. now, for some people their pets are their children. and in some more sweet news, a puppy who was lost in the desert for more than a month was returned to her owner. they had been separated in a car crash in late june that seriously injured the puppy and sent the driver flying through the windshield. they were unable to locate the pup until they spotted something last week, they used a cage filled with chicken treats as a lure, and the rest is a happy story. they sang the song, "bye, bye, bye." but for old fans of n sync, it

was hello, hello. the former boy band had a reunion at the vmas. of course, justin timberlake has had fantastic success as a solo artist, but he appreciates his roots. and to honor his old band mates, he brought them with him on stage to take them straight back to y 2 k, does this mean they were have a reunion? >> if we did anything like that, i think we would really come up with something real special where we could actually call it "the reunion". >> we hope. love reunions. so in this last week of summer we want to remind you to vote for your ultimate summer song. tell us what you think the best summer song ever is by tweeting us at "nightline." and your pick could be
