'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.

Everybody is influenced by someone.

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

I play Texas Hold'em on my Blackberry. I have amassed a fortune on that. I have almost 30 million dollars from playing. It is unreal.

Maybe sincerity is the new punk. But to me, I think I have to connect with something emotionally, on some level, or I don't care about it. And if I don't care about it, then I don't think anyone listening to it will, either.

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.

Once you sit in front of people and start playing songs, it's all on you. No matter what happens, it's entirely your responsibility the entire time. I like that intensity.
