Sadness is a very interesting idea, this idea of sadness being some kind of default setting that artists will go into. And then I started thinking about this idea of sadness and happiness, and the idea that sadness is very loud, and happiness is quiet.

I only ever really take out my guitar when I'm miserable, which isn't necessarily a very good time to do it.

I busked from the age of 13 until I was 18.

You know, albums are a funny thing. They're not like an intellectual decision. It's a collection of your kind of musings.

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?

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.

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.
