I think I'm alright as a lyricist, you know? But then what will happen every couple of months or so is that I'll hear a song I've never heard before and feel I've gone right back to square one.

I'm not even sure where home is. Probably Terminal 5. There is a strange sense of calm about arriving back at Heathrow.

Songwriters always reminded me of that kid at school who would go around with his guitar, like, 'Yeah, songwritin' man,' looking wistful. That wasn't me - those kinds of people put me off. In the early days, I'd write a bunch of lyrics and almost look at them as a sort of joke, to make the rest of the boys laugh.

I'm in a difficult position in the sense that, preposterous as this might sound, I don't like being the centre of attention. I get up on stage every night and play songs, but I almost feel the songs are the centre of attention. I don't like opening my birthday presents in front of people, either.
