The 25th Annual Putnam County Spelling Bee, Donmar Warehouse, London

The Broadway musical, as a habitat, tends not to throng with nature's great spellers. Gypsy's Mama Rose could probably get through "audition", without mishap, but the chances are that she'd put a middle "e" in "monstrous". And, even though it's her native German, how would Maria von Trapp cope with "Weltanschauung" – the word that happens to be the climactic clincher in The 25th Annual Putnam County Spelling Bee, a musical comedy (by William Finn and Rachel Sheinkin), that redresses the balance, to an almost parodic degree, in favour of the non-orthographically-challenged?

When I heard that he had written Polar Bears, a play about the stresses of loving a female with a bipolar disorder, my first cynical reaction was to wonder whether he has started to collect disorders for creative exploitation across the art forms.
