"Promises, Promises" the musical

at Elephant and Castle, very intimate space with a live orchestra - will be a great experience!  All I know is the Dionne Warwick song......
UPDATE:  It's based on the 1960s movie "The Apartment" with Jack Lemmon and Shirley MacLaine.  It was a superb production, on a tiny stage with no decor, props wheeled in and out by the singing actors, and the excellent score by Burt Bacharach and Hal David - I may have to see it again!
