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.

When my pop career was over, I was scratching my head, thinking, "God, how am I going to do something after I'm forty?" I was in my mid-thirties, thinking I was on the scrap heap.

You want to sing this song. And so it goes on until eventually, after - well, however long it can take - sometimes a few days, sometimes months - you piece the whole thing together.

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.

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.

I knew how the suits used to talk about the artists, with barely concealed contempt. So I knew what was waiting for me round the corner. Because I wasn't one of those very unusual people like Neil Diamond or Elton John, whose careers just seem to span the decades. I knew I wasn't one of them.

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.
