An Incident at the Border, Trafalgar Studios

Since 2004, the Ambassador Group’s Trafalgar Studios has done sterling work in staging West End transfers for some of London’s most promising fringe talents. Kieran Lynn’s An Incident at the Border arrives in the centre of town from the Finborough Theatre, where it was seen in July. It has a good cast and, because of its sceptical attitude to the pervading aesthetics of naturalism in contemporary playwriting, lots of promise. But can it live up to expectations?

Edinburgh Fringe: Tam o' Shanter/Trevor Noah/Bridget Christie

Tam o' Shanter, Assembly Hall ****

Scottish schoolchildren are brought up on Robert Burns but other British students aren't so fortunate. We may know snatches of the great man's work – “Wee, sleekit, cow'rin, tim'rous beastie”, “O, my Luve's like a red, red rose” and so on – but few of us could recite even a stanza of Tam o' Shanter.

Volcano, Vaudeville Theatre

The ever-libidinous Guy (Jason Durr) is "as subtle as a fire engine" when it comes to sex, or so we're told during the course of Volcano, and it's difficult not to feel that this belated Noël Coward discovery could be similarly described in theatrical terms. Never performed during Sir Noël's life, the 1956 play will constitute essential viewing for completists of the Master who want a further sense of how this protean talent's singular career evolved.
