I'm not into, Hey, what's your sign? or any of that. But I don't know how I got here, and I don't know how I write songs. I don't know why I breathe.

I just start singing some words with a tune. I don't ever write a song thinking, Now I'll write a song about... .

When I sit down to write a song, it's a kind of improvisation, but I formalize it a bit to get it into the studio, and when I step up to a microphone, I have a vague idea of what I'm about to do.

When I write, there are times -- not always -- when I hear John (Lennon) in my head, ... I'll think, OK, what would we have done here?, and I can hear him gripe or approve.

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.

It's not unusual for writers to look backward. Because that's your pool of resources. If you were to write something now, I bet there's a pretty good chance you'd call on your teenage years, your experiences then, stuff you learned then.

What I have to say is all in the music. If I want to say anything, I write a song.

A lot of artists use memories. A lot of prose writers, a lot of poets, a lot of songwriters, refer back to something. Generally it's all you've got, unless you're brilliant and can write totally in the now.

Sometimes you write a song in a certain era and it's got a certain kind of significance.
