I have a condition called Aspergers Syndrome, which is like a mild form of autism It means I don't interact properly in certain social situations.
I was a loner as a child and happiest at home, launching toy rockets and aeroplanes. When I started causing trouble in my third year at grammar school, Mum was really surprised. My parents sent me to a child psychologist, who suggested I might have Asperger's syndrome.
If you've been massive and it's all slid away, you tend to get written off. It's quite difficult to overcome that, which is why I've got this problem with nostalgia.
I met Gemma, my wife, when she was 12. She had a schoolgirl crush on me and her dad had arranged for her to meet me. Later, she started coming to my concerts, but I only got to know her well after her mother died. I rang to see how she was, and that's how it started.
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.
And I used to go the punk clubs such as a gay club in Poland Street that everyone would go to because it was the only place you could go to looking like that without getting beaten senseless.
I am very old-fashioned about marriage. It is for life and I mean it. I always knew that when I met the right girl, the life I had before - being single, in a band, girls everywhere - would be over.
My dad was a baggage handler at Heathrow and careful with money. He worked hard and had three jobs when I was young. I wish I'd inherited his care for money. Sadly, I've grown up to be rather scatty when it comes to finances.
I have always been far more interested in sound than technique, and how sounds work together, how they can be layered. I think electronic music, in its infancy anyway, allowed us to create music in a way that hadn't really been possible before. It created a new kind of musician.
I want to start my own airplane business. I'm going to buy two Dakotas, paint them up in war colours and do, er, nostalgia trips to Arnhem - you know, where the old paratroopers used to go - and charge them about 20 quid a time.
Being a display pilot is probably the thing I've been most proud of in my life. Don't really fly anymore now though. I have three small children and as most of my friends were killed in different accidents, I realised that it was probably just a matter of time before I went that way.
Song-writing is therapy for me. I'm a very moody person, very difficult to live with. There's a lot going on and a lot of contradictions. My life is always one step away from disaster.
Any time anyone says anything nice about me, whether it's Lady Gaga or your neighbor, it's a nice feeling, I'm very grateful for it. It's very helpful for your career. Every time someone says something complimentary it introduces you to their audience. It gives you credibility.
Strangely enough, when the Sugababes' 'Freak Like Me' went to number 1, which was built around my 'Are 'Friends' Electric' song, I had another song called 'Rip' go to number 1 in the Kerrang TV chart, so I was pulling new people in from very different areas of musical interest. That was quite an amazing week.
The idea of collaborating with anyone else was quite daunting. If Battles had any trepidation in asking me, I can assure you I had more after agreeing to do it.
I've got Asperger's syndrome and I'm not a very good people person, so I've always been more comfortable around machinery. Not in a weird way - I don't want to marry my car or anything stupid like that!
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 sometimes wonder if I might be a bit of a disappointment to people, because they are expecting all these '80s hits and what they get is a dark industrial wall of noise.
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.
When I was 11 I became a massive fan of The Monkees. We had a so-called 'band' of kids on my street and we'd go along to people's houses and mime to Monkees records.
