The masters of English operetta, lyricist/librettist W.S. Gilbert and composer Arthur Sullivan defined the genre and influenced all musical theatre after them. This comprehensive collection in this acclaimed "World's Great Classical Music" series presents 67 selections from 13 of their collaborations, including H.M.S. Pinafore, The Pirates of Penzance and The Mikado. The book features arias, duets and ensembles all newly engraved in their original keys for voice and piano. There is a biography of Gilbert & Sullivan, a plot synopsis for each show, and Gilbert's own illustrations of the characters.
