H.M.S. Pinafore

Gilbert and Sullivan's fourth piece together and the one that made them famous. Josephine, the captain's daughter, is in love with Ralph Rackstraw, a common sailor, while her father intends her for Sir Joseph Porter, First Lord of the Admiralty, who has never been to sea. Sir Joseph keeps insisting that all men are equal, which gives the couple ideas he did not intend. A late revelation sorts it out.
