Everything about singing, I learned from busking. Everything I learned about songwriting, I learned from busking. Busking, you learn people, you learn about reading people. You learn about reading the atmosphere of the street. If you stand still in any city long enough, you see everyone pass you by. It's almost like you get to know personality types, just by watching people walk past. You get a sense for things.

There's this unspoken thing that you have to wear a tux and some kind of nice dress. There are all these ethical rules, but I'm sure if you came to the Oscars in ripped jeans and a t-shirt they wouldn't throw you out. You would just look like a fool.

Certain songs have a life, and certain songs don't. A song is like a saddle: you ride it for a while, and if it's the right kind of song you can sing it for the rest of your life. And then other songs are only really important for certain periods of your life, and you move on from them and find yourself not necessarily needing to sing them anymore.

I'm not an actor, and I'll never call myself an actor. I've never thought of it as part of my life. I'll always be a singer, in my eyes.

I think inside every rock journalist, there's somebody who wishes they had the courage to live the life that they're not, and that they're writing about. But at the same time, inside every songwriter, I guess there's a wish for happiness.

I grew up wearing black arm-bands when the hunger strikers died. I went on those marches. I grew up basically a Provo, though I never obviously got into any activities. I was writing 'IRA, Brits out' on walls all over where I grew up, but that was a false sense of Irishness.

What happens to us all, I think, when we pick up a pen, is that we just become snobs.
