Sorry to hear Diz has 'gone before'. Back in 1971 or thereabouts the outfit I was playing with were doing a show at Nottingham University, and the agent had booked Diz into the show too. Diz turned up without a guitar. "That's okay. I knew you lot would have one," he said, and went on with a borrowed guitar (not a particularly fine instrument, an acoustic with round-wound strings and a two-inch action that my pal had bought for flumpence). Of course, Diz made it sound like a proper musical instrument. He had come up on the train and cadged a lift back to London with us ("I knew you'd be driving") and we dropped him in West Hampstead, where he went home to drink carrot juice - or so he said.
