Cancer is like a cockroach. It just comes back stronger. I'm tearing apart the immune system of the cockroach and seeing how it ticks. I've opened up my own pathology center.

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.

I've had a hip replacement, I've beaten cancer, I had my hand operation, and I stopped drinking. Something inside of me just went, 'I'm done.'

How many husbands have I had? You mean apart from my own?

I got my own back.

I mean it's funny, playing music, how of course you want it to do well, you want them to like it, but it's not competitive like an election, it's the Olympics, it's not a Formula 1 race. The Billboard charts are just to show you what people like.
