This guy is pretty good on the ukulele... Jamming... About 2/3 of the way through he starts jamming. Try to watch the whole thing.
Hey, that's Jake Shimabukuro. When I first read this thread I had a feeling that it might be him. He's a pretty big star in the Hawaiian music scene. And I went to the same High School as him, but he graduated the year before I enrolled. The guy definitely has some crazy ukulele skills.
