I'm also involved in the rights of the disabled and do some fundraising for that and I thought it would have been a big boost for the campaign but it couldn't be worked out.

George Lucas was casting about and had heard favourable things about my work in Clockwork Orange and asked me to come in, which of course I did even though no one knew what the film was about!

So I went to George and told him I had the opportunity to become the figurehead of a government safety campaign, and he agreed to give me the week off and reschedule shooting!

I'd worked in Clockwork Orange with Stanley Kubrick and since Stanley was such a prestigious director this opened all sorts of doors for me - one of them being Star Wars.

I think if you think of our lives as musicians, it's craftsmanship. We're not artists, we're more artisans. You know, I don't think we view ourselves as musical geniuses who can just make some sort of wonderfully beautiful record out of nothing. It's something that we work at. And if we keep working, hopefully we'll keep improving.

I am doing better now though one of my legs is shorter than the other due to the operations.
