Jekyll & Hyde is a 1990 musical based on the 1886 novella The Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson. Originally conceived for the stage by Frank Wildhorn and Steve Cuden, it features music by Frank Wildhorn, a book by Leslie Bricusse and lyrics by all of them. After a world premiere run in Houston, Texas, the musical embarked on a national tour of the United States prior to its Broadway debut in 1997. Many awarded international productions in various languages have since been staged including two subsequent North American tours, two tours in the United Kingdom, a concert version, a revamped US tour in 2012, a 2013 Broadway revival featuring Constantine Maroulis, and an Australian concert version in 2019 starring Anthony Warlow.
