I like being a big fish in a small pond. I'm not interested in a huge audience because it brings headaches.

You've got to really know your song, inside and out.

Well, this is shortly after the idea was put to me because it wasn't my idea to do a Christmas record. We can talk about that a little bit, if you like, later on. But I wrote that song actually about two days after the idea was put to me.

I'm an extremely slow worker, very unprolific. It can take me weeks to do a three-minute song, or at least to make it sound, in my mind, like I haven't written it. That's when I'm satisfied.

And as Craig Brown - he's an English humorist, not a comedian but he's just a writer and humorist - I'm quite a fan of. I heard him talking in a rather similar way on the radio. He said I'm the sort of person - I can't remember exactly what he said, but it was rather interesting - he said I'm the sort of person that can be reduced to tears in an empty church and feel like I'm the CEO of the Devil's organization in a full one, and I tend to feel like that as well. I love empty churches and going into them looking around, but I'm not a churchgoer at all.

The older I get, there doesn't seem to be anything remotely more interesting than talking about love and the lack of it and what happens when it's taken away from someone who's had it.

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.
