My fancy dress costume of choice is... something 1920s or 30s, when there was still so much elegance and attention to detail. An excuse for ultimate dressing-up indulgence.

I think that one day I won't have any kind of... sort of, or it will be either way, I won't have to think about anything. But at the moment, god I think probably because of what I do and the nature of how it is, I'm all over the place all of the time.

I think I'd like to be best friends with Björk, because I'd like to pick her brain a lot all the time and just have weird times together.

I met Prince William at a musical festival and he let me know he was a fan of my music. But the invitation to sing at his wedding reception came completely out of the blue. The fact that Kate and William knew the words to my songs was very touching.

You pick up loads of baggage with your first record with reaction to it from fans and critics. So I went to Ireland by myself for a couple of weeks with my guitar. I read lots of poetry, I read Patti Smith's autobiography and started words and phrases and then songs started to take shape.

I don't really have a style icon but I really admire the way people dress like Gaga, Rihanna and Gwen Stefani. It's good to be inspired by singers who write music and dress incredibly - rather than models and people in the fashion industry who dress immaculately anyway because it's their style.

Since I met Starsmith, my producer, I really feel like I'm making music because we write it together and produce it together. I've got a proper involvement in the end product as opposed to just writing a song and finding someone else to produce it.
