Meet the cast of freaks and uniques who gather nightly inside the wooden walls of the Spiegeltent, bathed in red lamplight, for a cabaret show with a couple of dark twists. There’s Agent Lynch – doing a sort of ‘Heidi does Carry On’ turn involving tiny cowbells, the tune of ‘Edelweiss’ and a pint of milk. And a fairly unexpected punch-line to her ditsy routine. Then there’s Mark Windmill (pictured), a bulked-up Marc Jacobs lookalike with his birds of paradise boylesque feather striptease. Mikelangelo, the self-dubbed ‘Balkan Elvis’, adds jaded weariness to his rude crooning, and Didj Wentworth writhes about gracefully on aerial straps, bare-torsoed and showered with rain (a toned-down version of the bath routine he used to perform as part of Soap! The Show).

TV magician Paul Zenon acts as a sort of comedy ringleader, compering the acts and adding tricks with everyday props including a bottle of Newcastle Brown Ale and a bowling ball. A Queen Elizabeth doppelganger tops and tails the show, putting the blue into blue rinse with her bawdy gags.

The Famous Spiegeltent, 0844 693 3008, until 26 Aug, 9.30pm, £20 (£17).
