As a busker, one thing that does not work is self-consciousness. A busker needs to be working. A busker needs to shed all ego and get down to work. Play your songs, play them well, earn your money, and don't get in people's way.

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 think it's very interesting, people who can't stand people who whinge and whine. It seems almost like a class issue. Because you think about who is the most positive, who's the most redemptive songwriter that's ever existed in your lifetime?

I've always felt that if I ever got cynical, I would have to stop making music because I'd just be poisoning the air.

I've realized, you know, having turned 40, that rest is just as important as work. In fact, it's equally as important.

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.

In Irish law, busking is considered vagrancy - you can be arrested for it. It's risky asking people for money in public. So it's not like it's a high-art job. And people who do it as a high-art job make very little money.
