Found this when I was looking for something else, it was taken (by me on a daft wee instamatic) backstage at the Glasgow Apollo on Thursday, May 31st 1979. The reflection in the mirror is one Fay Fife. This was the first ever Cramps show in the UK when they were opening for The Polis (as we'd call them up here). Setlist (in Bryan's handwriting) was: Garbageman, Rocket in my Pocket, The Way I Walk, Rockin’ Bones, I Was A Teenage Werewolf, Sunglasses After Dark, Human Fly, Twist and Shout, Weekend On Mars, Mystery Plane. Reproduced here from a page in NBT 9/10 that came out in 1979.
