Be cool and you'll be alright. That's rock & roll religion.

Most people don't know that I invented the selfie.

I just always enjoy it; if you really enjoy what you do, you don't want to stop.

One of my biggest thrills for me still is sitting down with a guitar or a piano and just out of nowhere trying to make a song happen.

I think the pop industry is still a young man's game.

Domesticity is the enemy of art. I don't know if that's true. You can write good happy songs. So, I don't think it's necessarily happiness. But I think self-satisfaction is maybe the enemy. It's kind of better to think, "Tomorrow night I'm gonna sing it better." There is this forward effort. It feels to me right, it feels human.

I never really got on that well with Yoko anyway. Strangely enough, I only started to get to know her after John's death.
