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 guess in a way I just feel blessed to be able to make music.

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

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

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.

If you stand still in any city long enough, you see everyone pass you by. So you're in Chicago. If you stand on the corner of Belmont and Clark, and you do that for three years, you'll pretty much have seen everybody in Chicago pass that junction.
