Sweet Charity is a musical with music by Cy Coleman, lyrics by Dorothy Fields and book by Neil Simon. It was directed and choreographed for Broadway by Bob Fosse starring his wife and muse Gwen Verdon alongside John McMartin. It is based on the screenplay for the 1957 Italian film Nights of Cabiria. However, whereas Federico Fellini's black-and-white film concerns the romantic ups-and-downs of an ever-hopeful prostitute, in the musical the central character is a dancer-for-hire at a Times Square dance hall.
