Just came across this video today, and I couldn't help but smile throughout the whole song. The video (below) is from the Hartford, Connecticut stop on the Ozzfest tour, where 10 year old Japanese prodigy Yuto Miyazawa just absolutely shreds the hell out of Crazy Train while Ozzy provides the vocals and the crowd goes nuts. The kid's got serious chops, pulling off pinch harmonics left and right while playing a Randy Rhoads-style Flying V.
Supposedly he's been playing since age 3, and whenever he's not eating or sleeping, he's playing guitar. Good for him, wish I had that kind of drive and determination. He's even played a show with Les Paul himself. (RIP, Les.) He recently was awarded a Guinness World Record for being the world's youngest professional guitar player.
Check this out, especially the solo part, it's great:
