World's Smartest Kids

Quinn Sullivan is a real-life 9-year-old guitar hero who's been wowing audiences since he first picked up the instrument at age 3.

After finishing his homework, this Beatles fan gets to work on his own music. His first original song is called, "Sing, Dance, Clap Your Hands."

Thanks to his talent, Quinn's is already going where few third graders have ever gone—onstage with blues legend Buddy Guy! "Buddy was a thrill. The first time I met him he's, like, 'You want to play riffs? You want to play a riff for me?' And I [said] yes," Quinn says. "He said, 'You want to come up on stage?' And from then on, I think he just wants me to play every time."
