This book includes: Gondoliers, Grand Duke, H.M.S Pinafore, Iolanthe, The Mikado, Pirates of Penzance, Ruddigore, The Sorcerer, Thespis, Trial by Jury, Utopia Limited, Yeomen of the Guard, and Patience. All of these plays/operettas were written 1871 to 1896. According to Wikipedia: "Gilbert and Sullivan refers to the Victorian era partnership of librettist W. S. Gilbert (1836–1911) and composer Arthur Sullivan (1842–1900). Together, they wrote fourteen comic operas between 1871 and 1896, of which H.M.S. Pinafore, The Pirates of Penzance, and The Mikado are among the best known. Gilbert, who wrote the words, created fanciful "topsy-turvy" worlds for these operas, where each absurdity is taken to its logical conclusion—fairies rub elbows with British lords, flirting is a capital offence, gondoliers ascend to the monarchy, and pirates turn out to be noblemen who have gone wrong. Sullivan, six years Gilbert's junior, composed the music, contributing memorable melodies that could convey both humour and pathos. Producer Richard D'Oyly Carte brought Gilbert and Sullivan together and nurtured their collaboration. He built the Savoy Theatre in 1881 to present their joint works—which came to be known as the Savoy Operas—and he founded the D'Oyly Carte Opera Company, which performed and promoted their works for over a century. The Gilbert and Sullivan operas have enjoyed broad and enduring international success and are still performed frequently throughout the English-speaking world. The collaboration introduced innovations in content and form that directly influenced the development of musical theatre through the 20th century. The operas have also influenced political discourse, literature, film and television and have been widely parodied and pastiched by humorists."
