Edinburgh Festival: Ilsa, Queen of the Nazi Love Camp

'It's not what it seems,' says the uniformed Nazi who introduces this sweet-and-sour musical with a goose-step. He is an ex death-camp commandant whose love for an SS whore gives the title for this play and whose search for the last phial of Hitler's sperm triggers its plot. But the facade of cabaret slips when he meets the real-life character Jim Keegstra, an Alberta schoolteacher who told his pupils that the holocaust was a hoax. Performances bristle with manic energy and David Rimmer's score brings bitter Berliner atmosphere, but the satire is never as terrifying as it intends. Traverse (venue 15), Cambridge St (031-228 1404). 11.00pm to 3 Sept (not Mon)
