This one is super cool, you can tell what a fan Jimmy is of Billy Joel. I mean as they do their bit here with the iPad you notice Jimmy visibly shaking, likely from nerves. He's so down to Earth, I think that's part of what makes him so perfect for his role on the Tonight Show.
I want this app. My wife and I will craft a classic song tonight. Instant classic.
