Phi-Phi
Phi-Phi is an opérette légère in three acts with music by Henri Christiné and a French libretto by Albert Willemetz and Fabien Solar. The piece was one which founded the new style of French comédie musicale, the first to really use the latest rhythms of jazz ( one-step, fox trot) along with a plot which emphasised comedy – with risqué dialogue of puns and anachronisms – more than the romantic style, which had predominated before. The success of the piece prompted imitators in Paris such as Le petit Phi-Phi (3 March 1922) and Les amants de Phi-Phi (13 March 1923). It also led to a spate of similarly titled stage works: Clo-Clo, Dédé, You-You, Pan Pan... A 1922 London production, in English, was very successful.
