The man who ignites the show is physical comedian Ben Langley. It’s hard to believe a man could generate such hilarity by pulling a rubber glove over his head and inflating it to beach-ball proportions. But it’s not so much what he does as the way he does it. Honed by 18 years of street performance in Covent Garden, Langley has that rare edge of barely contained anarchy that creates laughter from tension.
