Brock yesterday paid tribute to his old friend, saying they'd always had a "magical bond" when they worked together. Lemmy went on to form Motorhead in 1975, and the bands toured together two years later. Brock tells the BBC: "He was a great character, a great musician. He'll never be forgotten because he made a lot of great records."

Lemmy regularly said he'd been kicked out of the band for "doing the wrong drugs." Brock responds: "Our little joke, we always had, was that if he hadn't been fired from Hawkwind he wouldn't have formed Motorhead and gone off to this fantastic career and lifestyle that he had.
