Cc1 Test message Two hours ago when the Twitter verse learned we were going to do the next story on a young country star, hunter Hayes, a tsunami of messages from teens and tweens saying they would stay up past their bedtime to watch. Not that we condone such behavior the a sign how popular this guy is. Tonight you'll see why, here is my "Nightline" co-anchor, juju Chang. Reporter: Ten cities, ten concerts. In less than 24 hours without so much as a red bull. This 22-year-old country star is trying to break the world record for the most concerts in one day. Five, four, three, two, one! "Nightline" is riding along with hunter Hayes for a guitar-strumming, gut-busting race against the clock. You can say he is a young man in a big hurry. That's him jamming on the accordian at age 6 in the movie "The apostle." Hallelujah. Reporter: A prodigy who can play 30 musical instruments and write his song like "I want crazy." ? I don't want easy I want crazy are you with me baby let's be crazy ? Reporter: His debut album went platinum. Industry insiders see him as a legend in the making. This is my home. This is where I live. This is definitely the dream. You snow -- you know? Just to be here and get to do what we do, you know? I just hope I got to keep doing it. The only request, the only thing that weighs on my mind, what can I do to keep getting to do this? Reporter: As the opening act on Taylor swift's tour he became an instant favorite amongst teenage girls. He is surprisingly humbles. In some ways he could be the anti--bieber. You play every one of these? Not every one of these. This has got in a bit of control. Just being in this room period is a room coeam come true. That means we get to go on an arena tour now. I always dreamed of putting on a tour. Timed to the release of his second album "Story line" Hayes set his sights on a guinness world record, not just for glory, but for a cause. We are doing it with child hunger. Getting to spread the message about something we believe in. Reporter: Hayes will embark on ten concerts. Boston to Philadelphia, in just 24 hours. We will be with him every step of the way. I don't know how you prepare or if you really prepare for something look this. You just kind of. Got to roll with the flown something like this. Reporter: On hand the entire time, official time keepers from "Guinness." As the official timekeeper on the attempt it is important for me to measure that hunter does play for at least 15 minutes. I will be at every show ensuring those 15 minutes are met. Reporter: It kicked off bright and early in times square on the set of "Good morning America." Trying to break a guinness world record for most concerts in a single day. Here he is now. ? ? Reporter: Right after the "Gma" gig, he hopped a plane to Boston for concert number two. What's up, y'all? Reporter: It is 11:30 A.M. On a school day. But there are huge crowd of young fans everywhere. ? ? Reporter: Mouthing the word to each and every song. We started in New York, and in Providence, then New London next, and pull it off, we are going to Stanford after that. Are we ready to make some noise? Reporter: Mother daughter duo is following Hayes in concerts across three states. We ran into them, two shows later in Connecticut. We made it. We follow. We followed you on the road. That its your first cup of coffee? The whole time? Reporter: You would think Hayes would guzzle coffee or energy drinks he says the adrenaline of performing is his drug of choice. You look like you have so much energy you don't look tired. Great, that's my secret goal. I wanted somebody to say something to that effect. Reporter: Just an act or feeling that way? No, how I feel. When we get on this stage, natural adrenaline. Something that happens when the fans are in the room. Reporter: It is 10. 30. P.m. His 7th concert. The Ven ue is still jam packed. ? ? Reporter: More amazingly the tour is running ahead of schedule. How is your voice holding up? Are you feeling it, the strain? I have a lot of allergy issues. Ten cities, ten climates. You go through that in 24 hours you will experience things you never experienced in your life. I still have a voice. I am able to talk. Able to hit some notes I didn't think I would hit at this point. Reporter: 2. 30. In the morning in New Jersey, a very excited crowd inside waiting for hunter to arrive. You guys ready?
