The Potter pound is clearly far from running dry and anything associated with the boy wizard will still draw in those seemingly inexhaustible Potterheads. This production sets the action back in 1942 when Tom Riddle is a hormonal teenager who has not yet become Voldemort or lost his nose. There's a battle of the bands, a murder plot and a lot of credible musical numbers covering a variety of styles. The production zips along at a fast pace with a simple plot, ribald humour and moments that play on the audience's sympathies – Hagrid elicits the most 'awwws' – not dissimilar to a pantomime.

The material that strays furthest from the source fares the best. The pervy painting is especially good, combining a fun musical number with a bit of smut while questioning an often unexamined aspect of the Hogwarts infrastructure. When the Golden Trio of Hermione, Ron and Harry do make an appearance, the characters are lazily sketched and accompanied by the worst Alan Rickman impersonation ever. Overall, it's a slick, light-hearted romp, and with so many shows to choose from at the Fringe, this parody musical is a dependable, if not challenging, option.

Assembly George Square Studios, until 25 Aug, 5pm, £13–£15.
