The last musical score that Coward ever wrote was for this Harry Kurnitz musical. Based on the play The Sleeping Prince by Terence Rattigan, it follows the fortune of American-born chorus girl Mary Morgan in 1911 London and her relationship with Archduke Charles of the eastern european country Carpathia. Oh, and the Duke's teenage son, mother and local fish merchant Ada Cockle are all along for the ride. Including the sprightly numbers I've Been Invited to a Party and How Do You Do, Middle Age?, it's just as fizzy and drolly humourous as you'd expect from a Coward and Kurnitz (writer of One More, with Feeling!) collaboration.
