Written more than a century ago and initially regarded even by their creators as nothing more than light entertainment, the fourteen operas of Gilbert and Sullivan emerged over the course of the twentieth century as the world's most popular body of musical-theater works, ranking second only to Shakespeare in the history of English-language theater. Despite this resounding popularity and proven longevity, most books written about the duo have focused on the authors rather than the works. With this detailed examination of all fourteen operas, Gayden Wren fills the void. His bold thesis finds the key to the operas' longevity, not in the clever lyrics, witty dialogue, or catchy music, but in the central themes underlying the characters and stories themselves. Like Shakespeare's comedies, Wren shows, the operas of Gilbert and Sullivan endure because of their timeless themes, which speak to audiences as powerfully now as they did the first time they were performed. Written out of an abiding love for the Savoy operas, this volume is essential reading for any devotee of these enchanting works, or indeed for anyone who loves musical theater.
