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.

Fame doesn't make it hard to date, because I could be seeing someone now and no-one would know. But if you go out with someone who's in the public eye you're asking for trouble. It's double intensity, double scrutiny. Even if I just went on one date with a normal guy, word gets around and that freaks me out. I don't like all that gossipy stuff.

Lauryn Hill is quite political and is very bold and isn't afraid of wearing her heart on her sleeve, and same with Bjork, except she is a little bit more kind of fragile.

I've always said that Adele has turned so many people on to British singers - whether female singers or just like music from this country in general.

I still don't know if I can write songs. I don't think anyone ever knows if they can write songs.

By the time I got writing 'Halcyon,' I was on a roll, and I realized I had so much to write about, I realized I had so much built up inside that I couldn't really alleviate before, and then all of a sudden it was like reservoir burst.
