Smile to the future and it will smile back to you

Fracking is an incredible risk to the human race, I don't know why they even thought of doing it.

I never wanted to be a professional artist; I think that's limiting.

People make music to get a reaction. Music is communication.

I really feel that artists or musicians are controversial people. Controversy is part of the nature of art and creativity. If people are not doing that, they're not artists - they're artisans.

Not being appreciated for 40 years or something ... It feels like I was accused of something that I didn't do, which was breaking up the Beatles. That was like being somebody who is in prison without having done anything wrong.

I think something that's very important for us to communicate is usually very simple. Like breathing: Breathing is very simple. You don't do a dissonant 9th harmony or something in breathing. You just breathe, you know. I think that's how it is with very important messages.
