I've always felt quite like an outsider. I don't really belong in the mainstream, and I quite like that.

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.

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.

Cruel to be kind means that I love you.

I felt that in order to do what I wanted to do, I had to do certain things, and one of them was to have a hit in my own right. At least one.

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.

Later in life, suddenly, if you're an outsider, it's something to be celebrated, I think, rather than getting on people's nerves.
