The Roundhouse becomes a village green with a difference for this vintage circus showcase from Vanessa Toulmin, director of Sheffield's National Fairground Archive. Expect to see original mid-century sideshows, aerial performances, contemporary cabaret; a promenade experience studded with headless ladies, girls in goldfish bowls, 27,000-volt women, with Miss Behave, Marawa the Amazing and the Insect Circus on hand.
