But anyway, I was convinced that it would go away, you know. But the idea was that he was sitting on a flight - you know, one of those sort of fairly long flights, like, sort of, you know, Newark to Denver or something like that - so, you know, a few hours.

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 sort of have various sort of theories when people ask me about songwriting because it is a mystery. You don't really know. Sometimes you can do it and sometimes you can't. It's really peculiar.

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.

And then, one day, they program a new tune, and it really catches your ear, you know, because you can be doing the washing up or something, you know, in your apartment and suddenly you go, whoa, what are they playing in there? And you run to the wall, but it's finished - but the song's finished. You only heard enough of it just the pique your interest. And you never know when they're going to play it again, of course, like a normal radio station.

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.

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.
