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.

"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 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.
