re: Sprinklemist's comment, The Pirates of Penzance remains one of the most popular of the G&S plays, exceeded only by The Mikado (which may be the most popular light opera ever written) and H.M.S. Pinafore. Those are often called "the big 3". Those plus The Gondoliers are sometimes called "the big 4".
