The Gaiety Theatre was a West End theatre in Westminster, London, located on Aldwych at the eastern end of the Strand. The theatre was first established as the Strand Musick Hall in 1864 on the former site of the Lyceum Theatre. In 1868, it became known as the Gaiety Theatre and was, at first, known for music hall and then for musical burlesque, pantomime and operetta performances. From 1868 to the 1890s, it had a major influence on the development of modern musical comedy.
Under the management of John Hollingshead until 1886, the theatre had early success with Robert the Devil, by W. S. Gilbert, followed by many other burlesques of operas and literary works. Many of the productions starred Nellie Farren. Hollingshead's last production at the theatre was the burlesque Little Jack Sheppard (1885–86), produced together with his successor, George Edwardes. Edwardes's first show, Dorothy, became a long-running hit. In the 1880s and 90s, the theatre had further success with a number of burlesques with original scores by the theatre's music director, Wilhelm Meyer Lutz, including Faust up to Date (1888), Carmen up to Data (1890) and Cinder Ellen up too Late (1891).
