I record stuff all the time, like little vocal things. I write random things down... Sometimes I just get things stuck in my head and I record them, and that actually becomes a song quite a lot of the time.

It's good to talk sometimes. Sometimes interviews are really good for you... You end up evaluating yourself more and talk about stuff that an ordinary person wouldn't necessarily keep revisiting. I used to close myself off and want to be alone, but now I'll call a friend. When you're in a relationship, they're that person.

Cover versions, that's my forte, that's all I ever used to do. When you play your own songs, it's quite scary, 'cause I'm quite honest and open, they can be very revealing. But covers, I don't have to think about, just get me up there!

I'd hate it to become style over substance, I'd hate people to start putting me in a magazine article about my style. I don't like dressing up in something I'm not necessarily comfortable in just to make it more of a show. I want the power to come from what I sing about and how I sing.

I maintain that when I finally retire from my career in music, I will go and live back in Wales - when I am an old person, if I live to be an old person. The water I miss, and the air, there's something different about it. And I miss the simple life.

I'm quite private. And I never wanted to be the biggest star in the world really. So in that sense I've got a good balance of doing great shows, of making an appearance every now and then and writing music, and I don't really have to do much else.

Every day I'd say I look different. Sometimes I look really formal, sometimes I love the classic Stella McCartney, Chloe Sevigny and Gwyneth Paltrow thing. Other days I like being rock star and wearing leather jackets and studs. I love wearing Burberry - it's the perfect combination of formal and punky.
