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 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.

You try to make every word count, so there's no doubt what you're talking about. When you're young, you waffle away. Well, I'm done with that. I think it's much more interesting to say just what you mean.

You know, where have you - what have you been doing? You know, and you find yourself sitting next to Jesus, and he's rather an agreeable man. And you have an opportunity to say, so what went down then, you know, that night? And it's supposed to be like him just sort of telling you very conversationally. That was the idea I had. Whether it - whether it comes - came off or not, I don't know.
