A large stage awaits, with wooden boarding as a partial backdrop, a couple of crates and large yellow balls. Intriguing. After a hiatus of ten years, DON GNU returns to Edinburgh with M.I.S All Night Long. Two men appear, suited almost identically, with similar moustaches and slicked back hair: men in sandals. They are carrying a large piece of boarding – seemingly the missing segment to the stage backdrop – through the audience, clambering over and around them to the stage.
