Todd Rundgren

I'm a guitar player, really - I mean, first and foremost - I grew up with all that great 1960s music, in terms of growing up, becoming a musician, so it's like first-love stuff; I'm always going to go back to it.

If I wasn't acting, I'd try and be a footballer. I wouldn't be a musician because I can't write my own music. Realistically, I'd probably do something with dogs, like a vet or something. I love animals.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
