jekyll & Hyde is a musical horror-drama loosely based on the novella 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 Wildhorn, Bricusse and Cuden. 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 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 re-vamped US tour in 2012 ahead of a 2013 Broadway revival and an Australian concert version in 2019.
