Oh, Captain! is a musical comedy based on the 1953 film The Captain's Paradise with music and lyrics by Jay Livingston and Ray Evans and the book by Al Morgan and José Ferrer. The basis of the musical was the 1953 film The Captain's Paradise, which had been written by Alec Coppel and Nicholas Phipps. The musical updated the film's Gibraltar and Algiers setting to London and Paris. The production was dismissed by the critics as a "tired businessman's show", but the cast and choreography were much praised.
