I hate to use the word perfect because if you look hard enough you will inevitable find a flaw but both in watching and on reflection I can find nothing bad to say about DC Moore's play Straight. It is as if the stars of script, direction and performance aligned.

Straight's central premise is a drunken challenge between two university friends - Lewis (Henry Pettigrew) and Waldorf (Philip McGinley) - who are reunited after Waldorf returns from seven years travelling.

Lewis is married and thinking about starting a family with his wife Morgan (Jessica Ransom). Waldorf burst into their settled idyll - well cramped studio flat - with tales of adventure and sexual exploits. To say that Lewis re-evaluates his own life as a result would be doing the plot a disservice but I think to explain the challenge and how it changes the men's friendship and the relationship between husband and wife would be too much of a spoiler

Straight is an adaptation of the film Humpday and what you get is a script crackling with wit, humour and carefully observed behaviour. It was interesting and intriguing and under Richard Wilson's direction performed with perfect pitch - an achievement considering it is essentially a comedy about sex. It is laddish without being crude and exploitative; a situation that is contrived without being farcical, funny without being silly.
