We [with David Cunningham] did do Top Of The Pops. It was an eye-opener. I mean, one of the things that was so interesting - I've talked about this a few times recently, and people can't believe it - they used to do this thing called tape switch with the Musicians Union.

I guess we all had that work ethic. None of us were rock stars, so if you had time in a studio, it was a big, big deal: you're not going to sit around taking drugs and drinking and waste it, you'll do something.

At that time, 73 and 74, I became aware that there were a number of us making instruments. Max Eastley was a good friend and he was making instruments, Paul Burwell and I were making instruments, Evan Parker was making instruments, and we knew Hugh Davies, who was a real pioneer of these amplified instruments.

One of the nicest things is that I still get, very ambiguously, people saying to me, "Oh, I'm just reading your book." And I say, "Which one, for God's sake, I've done six now!" "Oceans of Sound".

David's [Cunningham] a very interesting character. He has more integrity than is good for him. So, everything he did after that sort of undermined what he'd done. Other people who kind of took life more cheaply, would have really gone for it. David almost did everything he could to scupper the whole thing, which I very much admire, but of course it was deeply irritating then, because we wanted to make a bit of money! So we made this very catchy tune and then he added a bunch of weird stuff which was all very strange.

I needed a huge amount of energy to cope with my life. I had a huge amount of energy where stuff was concerned: it was as if all this unconscious material had been unleashed.

I'd entirely forgotten about Pass The Distance, and then I went to Japan in 2000, and was asked to do interviews with all these journalists, who were showing up with bootlegs of this record, asking me to talk about it. I was astonished. It kind of gained momentum.
