My latest theory is that it's - well, I describe it as, like, being in an apartment with kind of thin walls. And in the apartment next door, they've got a radio tuned constantly on - tuned to a really cool radio station. It's on all the time. And you can just hear it coming through the wall all the time.

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

London was a real dump in the 70s, when it belonged to me and my friends, because, like most cities, you kind of hand them off. You're in charge for a bit and then you don't go out anymore. You say, "Oh god, it's going to be too crowded."

Going to Nashville to meet the in-laws was the first time when I'd been in America and not been seen as some sort of eccentric character with a cute accent.

So you can be about your business, and then on it comes again. And this time you're ready, and you've got a wine glass or something. And you put the glass up to the wall, and you can hear through the wall a little bit more of the song - maybe just the middle bit this time. You know, you managed to get in a little bit of the end. And so it goes on until - because you just got to - you really just want to sing it.

"I Wish It Could Be Christmas Every Day," which I actually recorded on "Quality Street" because I don't think anyone has ever covered it before. You hear it every single Christmas, and it is a great record. That's by Wizzard. It is a really great record, but I don't think anyone's ever covered it before, so I had to go it doing it differently. It's quite different from how the original goes.

I'm really lucky that I've had a little gang of people who I've been involved with for a long time... I've been really lucky to have a gang of people who have always been there to encourage me to get on with it. Styles come and go, but I try not to take any notice of that.
