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.

I've always felt quite like an outsider. I don't really belong in the mainstream, and I quite like that.

And the other thing for the sort of posher kids was a sort of lethal scooter, you know. One of the things that you just push along with your - really heavy, lethal, you know, trap your fingers in and every bit of metal got rusty very quickly. And the girls I seem to remember they had a thing like a broomstick with a horse's head on the top which they sat astride.

When punk rock came along, the one thing you were not supposed to be was musical.

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.

It's like a little folk song. I think it might've been Harry Belafonte or someone like that who did it. And "Merry Christmas, Everybody" by Slade, which is a rock group - a rock-pop group who are very big over there.

The idea was put to me, and my initial reaction was of slight sort of - I was slightly appalled, really, because in the U.K., we don't - we think it's all a bit vulgar, you know, doing Christmas or cashing in on Christmas. And there's a word we have for it, which is naff. And it's not exactly uncool. It really sort of means kind of vulgar and a bit - not very stylish.
