Jonathan Harker leaves his fiancée Mina to go to Transylvania, where he has some business to transact with the mysterious Count Dracula. When he gets there, he finds a jazz-handsy vamp obsessed with travelling to England and auditioning for Andrew Lloyd Webber. With a title like that, it was never going to be too faithful to the source material, was it?

Last Chance Saloon’s take on the Dracula myth has a lot counting against it: constant references to Lloyd Webber and John Barrowman and excruciatingly cheesy covers of contemporary pop songs (‘Suck You’ by Cee-Lo, anyone?) threaten to lower it to the level of an ITV variety show. And yet, despite these San Andreas-sized faults, the performers’ natural charm saves the day. Simon Naylor’s Van Helsing in particular is a delight, channelling Mike Myers’ Goldmember without ever straying too far into plagiarism, while certain set-pieces (such as the boat trip across the Channel) display an ingenious wit. A pleasure, albeit a guilty one.
