Comedy duo Flo & Joan’s irreverent boutique musical about the master of the form, Andrew Lloyd Webber, is a devilish wheeze, superbly executed. It finds the Dempsey sisters taking back seats for their Fringe theatrical debut (on piano, drums and backing vocals) with George Fouracres centre stage as the oft-maligned and litigious impresario. It follows his life, from difficult youth as a bullied child with only a mass of privilege and connections to pursue his dream of ruling London’s West End, to the initial blaze of success collaborating with Tim Rice.

Tracking the fallow period, the Phantom years, the loves of his Sarahs (plural) and Margaret (highly singular), the piece charts Webber’s international rise, fall and well, let’s be charitable, consolidation of his reputation, with a bathetic, sweeping scope worthy of his own overblown productions (albeit adjusted for budget). Flo & Joan's qualified love for their quarry shines through in the musical homages, while the sprightly and versatile Fouracres imbues the preening, prickly lord with overweening ambition, pathos and consistent hilarity.
