I can remember a lot of nights performing in those early years where you felt that you hit some good moments, but a lot of the time you're thinking, "Oh, God, this isn't quite making it." So I think that is what makes you in the end refine your view of things a little bit.

You don't want to believe everything you hear.

No one can replace Richard Wright. He was my musical partner and my friend.

I think I could walk into any music shop anywhere and with a guitar off the rack, a couple of basic pedals and an amp I could sound just like me. There's no devices, customized or otherwise, that give me my sound.

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.

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 find it incredibly difficult to write anything that's really happy.
