Muleskinners’ Tweddell? No. It’s the guy from Gun, Paul Gurvitz, in black and white print of a wide-spectrum colour show.

Photograph by Colin Fulcher of Paul Gurvitz reversed left to right. The Gun at the Speakeasy 1967. This is mos’ def Fulcher’s first light show – see those rippling bubbles melt. That’s what he told me. It is not, as I first thought, the Muleskinners. I now am sure it’s The Gun at the Speakeasy in 1967.
