I found myself in Zurich Airport. I'd done a TV show, oddly enough, with Mavis Staples. That's the way they do it in Switzerland. And I'd had a bit of a late night with members of her band. And I was - my flight was delayed. And I was sitting in the airport, and I just came up with the idea. And by the time, we landed at Heathrow, I'd pretty much sort of got it.

If a hit came along, I wouldn't be unhappy about that. But I'm a bit too old for that now-doing videos and all those types of TV shows. I've kind of done all that, in the '70s.

When somebody like Elvis Costello comes along, anybody can make a good record with him.

I realized sometime in the early '80s that if I didn't do something - like planning for the future in a way, a kind of pension or something - that if I didn't do something there and then, I was going to be condemned to forever present my three years as a pop star, condensed, as a stage act for the rest of my life. Because that's normally what happens to people in the pop business.

Even if I was really prolific - which I'm not - I think I'd always put at least a couple of covers on my record. I think it's a sort of healthy thing to do. It shows that you're not totally self-obsessed.

I don't have the faith now. I certainly believe in Jesus - you know, that he existed and he was a very nice man. And who can disagree with a simple philosophy of treat other people like you'd like to be treated yourself? It's absolutely - nothing I can disagree with that.
