 Within a decade the focus began to shift from melodrama to operetta and opera, so the theatre also came to be known as the Gaîté-Lyrique.In the early 1920s Diaghilev's Ballets Russes danced here, and after World War II it was used for musical comedy.In the 1970s attendance decreased, and there were several attempts to find new uses for the building, culminating in 1989 in the construction of a short-lived amusement park, that resulted in the demolition of most of the theatre, except for the facade, entrance and foyer.
