Edinburgh Festival Day 19: Reviews: Lust

Aware that nothing sells a show like sex, Iain Heggie has called his wry new monologue Lust. It might have been called Zealotry. On finding that his girlfriend Muriel has had previous lovers, tweed-jacketed and tank-topped Duncan wraps himself in his college scarf and embarks on a campaign to rid the world of its baser passions. The premise of the play is ripe for excess, but despite the potential for low farce (Duncan becomes a pornographer's assistant), Heggie's script never sinks into caricature. Forbes Masson controls the audience with nothing more than an impeccable Morningside lilt, raised eyebrows and pursed lips. There are plenty of talking heads on the fringe, but this is one that Alan Bennett might have enjoyed most.
