David Lee Roth had the idea that if you covered a successful song, you were half way home. C'mon - Van Halen doing 'Dancing in the Streets'? It was stupid. I started feeling like I would rather bomb playing my own songs than be successful playing someone else's music.
When I pick up the ball and it feels nice and light and small I know I'm going to have a good day. But if I picked it up and it's big and heavy, I know I'm liable to get into a little trouble.
