Thoroughly Modern Millie is a musical with music by Jeanine Tesori, lyrics by Dick Scanlan, and a book by Richard Morris and Scanlan. It is based on the 1967 film of the same name, which itself was based on the British musical Chrysanthemum, which opened in London in 1956. Thoroughly Modern Millie tells the story of a small-town girl, Millie Dillmount, who comes to New York City to marry for money instead of love – a thoroughly modern aim in 1922, when women were just entering the workforce. Millie soon begins to take delight in the flapper lifestyle, but problems arise when she checks into a hotel owned by the leader of a white slavery ring in China. The style of the musical is comic pastiche. Like the film on which it is based, it interpolates new tunes with some previously written songs.
