Librettist W.S. Gilbert, created "topsy-turvy" worlds, where each absurdity is taken to its logical conclusion. Fairies rub elbows with British lords, flirting is a capital offense, gondoliers ascend to the monarchy, and pirates turn out to be noblemen who have gone wrong. Sir Arthur Sullivan contributed memorable melodies conveying both humor and pathos. Gilbert and Sullivan introduced innovations in content and form that directly influenced the development of musical theatre through the 20th century. Their operettas influenced political discourse, literature, film and television and have been widely parodied. Gilbert & Sullivan Opera Gala is an evening featuring the music of W.S. Gilbert and Sir Arthur Sullivan that pays tribute to the many successful G & S Operettas performed at the Courthouse.
