Turning the Roundhouse's main space into a sort of village green carnival, Professor Vanessa’s Wondershow will hark back to the fairground sideshows of the 1930s-1950s, with circus, cabaret and variety from artists including Miss Behave, Marawa The Amazing, Jon Marshall and his Sideshow Illusions, and The Insect Circus. The whole thing has been conceived and directed by Professor Vanessa Toulmin, the director of the National Fairground Archive in Sheffield.
