(Vocal Score). The Pirates of Penzance , premiered in 1879, confirmed the comic genius of librettist W.S. Gilbert and composer Arthur Sullivan, following on the heels of their wildly successful H.M.S. Pinafore . Pirates invade the rocky coast of Cornwall in this topsy-turvy tale of love and duty, highlighted by the famous strains of "Poor Wandering One," "I Am the Very Model of a Modern Major-General," "Oh, Is There Not One Maiden Breast" and "With Cat-Like Tread, Upon Our Prey We Steal." This vocal score includes the complete music and all dialogue, a plot synopsis, articles on the famous partnership and the history of The Pirates of Penzance , a filmography and a discography.
