We've updated the show for the Nineties while at the same time remaining faithful to the original Fifties feel. It's been sharpened up and made less saccharine. Most musicals accumulate a few barnacles as they get older, and this is no exception, so we've gone back to the original and made it harder-hitting and raunchier. The score for the film version was very syrupy, and we've gone back to a brassier, harder sound that is more appropriate."
