If I'm going to go out to be a solo artist, it's because I want to do something different without having to wait on someone else's schedule or hobbies or be limited by other people's prejudices. I'd be kind of stupid not to exercise that.

'The Beatles' did whatever they wanted. They were a collection of influences adapted to songs they wanted to write. George Harrison was instrumental in bringing in Indian music. Paul McCartney was a huge Little Richard fan. John Lennon was into minimalist aggressive rock.

I've had a long career and I want to continue to have a long career. The way to do that is not to go away.

If I had a musical identity that was definable then it would be time to get into painting or something else. Race car driving.

I feel like you're not a real musician or entertainer if you can't go into a room, pick up an instrument and entertain people.

If you're an American kid, you can't help but be influenced by Led Zeppelin, Black Sabbath and the Rolling Stones because they're always on the radio.

In the United States, workouts tend to focus on body image and how you look. For me, it's really all about the brain.
