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.

How much in life is determined, and how much is due to chance?

I haven't watched it [the film 'Pink Floyd at Pompeii'] in years. I find it excruciating.

I don't even think whether I play the blues or not, I just play whatever feels right at the moment.

I don't have a very disciplined approach to practicing or anything, but I do tend to have a guitar around most of the time, which I strum on most of the day.

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.

I tend to fly old airplanes and old sort of things that are nearly about as old as me. Biplanes and stuff like that.
