I don't know what you wanna describe as Rock 'n' Roll, but I certainly thought that 60s stuff, Bob Dylan and the Beatles, changed the world a little bit. But the effect seems to have retreated. I think it's harder than we think to change the world. These things go in cycles. It doesn't seem to have done an awful lot of good, does it? You know, all the talk of racial harmony and equality in the world... we haven't got a long way since the 60s.

We mixed the sounds ourselves. If they were going to put the sound back onto our film [Pink Floyd: Live at Pompeii.], we wanted to mix it ourselves.

Usually, in the studio, on this sort of thing... you just go out and have a play over it, and see what comes, and it's usually - mostly - the first take that's the best one, and you find yourself repeating yourself thereafter.

My technique is laughable at times. I have developed a style of my own, I suppose, which creeps around. I don't have to have too much technique for it. I've developed the parts of my technique that are useful to me. I'll never be a very fast guitar player. I don't really know what to say about my style. There's always a melodic intent in there.

I don't live my life on the road. I'm getting on a bit and there's a lot of other things in my life. Our lovely children and their lives. It's more of a part-time business these days.

I'm afraid I haven't become a born-again Christian. I'm sort of 'Church of England, lapsed' is about as far as I go.

I haven't felt compelled to go back in the studio and do anything serious. I have a little sort of home studio thing which I potter about in occasionally.
