I speak onstage to try to establish some method of communication. The songs are supposed to be a way of communicating. But speech and drinks and sometimes chocolates are also a way of communicating.

You try and imagine what it must have been like to first see something moving on a screen. It must have blown your mind, because up to then life went by and there was no way to capture it. You could only get one instant and you didn't get the movement. So it's like having a bit of control over time really, because it's happening in real time or what seems to be real time, and then you can play it backwards and you can watch things again and again.

I've stuck to the same things for twenty years. I try to look like a slightly edgy geography teacher. Like what a geography teacher looked like when I was in school. Cords, sensible shoes and glasses. I never liked geography much as a subject though. In fact the only geography teacher I can remember from school was a woman who had a moustache.

Hawkwind are one of those bands that people introduce you to because you don't see them on the covers of magazines. I'd heard 'Silver Machine' but Russell Senior, who was in Pulp, got me into them. They had a song called 'Master Of The Universe' and we nicked the title in 1985 for one of our songs.

Every woman I've had a relationship with has found this maddening; the fact that I will talk about anything on the stage, and reveal all this stuff, and yet when I'm at home, I clam up and won't discuss anything intimate or personal.

In a song you can kind of stage-manage everything so that it puts you in a good light. And once a song is recorded, it always performs well.

If you perform on a stage or you sing a song, it's like you sing your song, and then the words go into the air, and then they go into somebody's body through their ears, so it's kind of like penetrating somebody. It's kind of like having sex with somebody - but, obviously, from a great distance.
