The chorus sings with real gusto and dances prettily when required. In the role of Stanley, “the very model of a modern major-general”, to quote his showpiece aria, Richard Suart demonstrates that, in the matter of patter, he is still a force to be reckoned with, and John Savournin blusters and bellows winningly as the Pirate King. The star comic turn is the small troupe of coppers, led by James Creswell, who turn A Policeman’s Lot is Not a Happy One into a marvellously silly song-and-dance routine.
