Maybe if my songs feel personal, that's very nice. I like that. I take that as a great compliment.

I split it up into working on the two narrative pieces that can tell a story. The scariest thing was whether I'd be any good performing live again. It was such a long time since I'd done any live work. It's so different for me than recording. Every night my audiences were what I would dream of. You could just feel their support.

Even just making albums - which was more within the structure that I've worked in for years - you have no idea how people will respond. You don't know if it'll be any good whatsoever. It can be terrifying.

What I've tended to do is to use my own experiences to get into someone else's mind, like in Wuthering Heights.

There are a lot of very strong connections with music and mathematics. They both can work in patterns and sequences and repetitions.

That doesn't matter. If it speaks to them and they get something positive from it, it's great.

I suppose in some ways doing some of the songs in the show felt a bit like I was doing cover versions. I was covering myself. Not that they didn't feel like my songs, but the way I was approaching them was from a place so outside where they were written. The fact that these songs were in the context of a live show was a new thing.
