Costume and character changes pass in a flash and the resultant mayhem means there’s rarely a dull moment. The script has its roots in 1980s improvisational comedy on the California college circuit and has remained essentially undergraduate since. Sadly the American accents have not undergone an upgrade. Those taking part get stickers, if the intended level of comedy needed further underlining. The sheer unstoppable energy means there’s plenty of occasion for laughter but, in truth, that’s more down to the relentlessness of the performances that the quality of the material.
