Opera della Luna is a little miracle: Curtain Raisers at Wilton’s Music Hall reviewed

Arthur Sullivan knew better than to mess with a winning formula. ‘Cox and Box, based on J. Maddison Morton’s farce Box and Cox’ reads the title page of his first comic opera, composed to a libretto by F.C. Burnand a good five years before he latched up with W.S. Gilbert. ‘Those boys hit on a brilliant idea,’ Billy Wilder is supposed to have said when he saw the musical that Andrew Lloyd Webber and Don Black had created from his movie Sunset Boulevard. ‘They didn’t change a thing.’ Gilbert’s comic beats are sharper and faster; and he’d doubtless have shortened it by about 15 minutes. But Burnand’s words gave the 26-year-old Sullivan the hook he needed, and on a late summer night at Wilton’s Music Hall, Opera della Luna took it from there. The woman directly behind me started laughing in the overture, and didn’t stop for the full hour.
