Album sales have collapsed, with few artists making money from albums; touring is more lucrative. But I'm 53 now and won't be able to tour forever, so a logical step is to get into writing film scores. Trouble is, you need to be somewhere which has a big film industry - another reason why I'm thinking about living in California.

I'm very intolerant and I get fed up with people easily.

I always say it took me 10 minutes to write 'Cars,' but if I am honest it could have been even less than that - and it has been a really successful song over the years. It is still massively used, in advertising, in films, and people do cover versions of it a lot.

I actually have two hats in my office; one says "network," one says "studio." Paul Lee over at ABC sent those over to us and I find it very useful.

I think any song should sound good just played on a solitary instrument with the vocal. If you have those basics you have all you need. The production then just polishes that idea into the finished thing.

I've spent a lot of time in the United States and I'm not under any illusions that it's a crime-free nirvana. I'm well aware it has plenty of problems, though they seem to be associated with particular areas.

I became famous so quickly and so young - it was daunting. I was immature and I used to say some really stupid things in interviews. I never smiled on stage so I looked really serious, but it was because I hated my teeth and was incredibly nervous.
