I'm surrounded by good people. That's the measure of a good life. All the rest is flotsam.

I used to take amphetamines until I realized that amphetamines didn't go with being a good singer.

I love Adele. That's a lead singer; that's the real deal.

You have to keep fit being a singer - that's part of the job. You can't do it unless you have incredible stamina.

Imagine if you could go watch Mozart today, even if it's the last, crappiest show he ever played. What a thrill that would be.

When I sing, I try to live the song or live the emotion of the song. The space I'm in doesn't exist. It's another world.

Rock n' roll seems to have changed society much more than any politician, I think it really has.
