I think an encore is perfectly acceptable, but I find it so weird when people do two or three.

I've learned not to hide behind a veil of irony - to talk about my work in a more honest way.

I've always been a bit of a decorator. I think if I wasn't a singer I'd probably be in stage setting or interior design or something. I like clutter and I'm quite visually greedy. I can't have things to be plain; I have to have things looking interesting maybe I'm just a frustrated interior designer stuck in a singing career.

The first album, for better or for worse, was done over from the ages of 17-22, with a couple of different producers. Some of it was recorded in an old swimming pool, some of it was recorded in a synagogue - it kind of was all over the place.

The stage is the place I feel comfortable - it's almost as if real life is where I feel most nervous. Conversations are a lot more nerve-wracking.

I'm one of those people that is up for most things. When I was offered to sing at the Oscars I was like, 'Yeah, I want to know what that's like!' I'm always curious to know what things are like - as long as you're not compromising who you are.

The Teenage Cancer Trust does incredible work supporting and caring for teenagers and young adults with cancer, and it's a cause that is really close to me and my family.
