Finian's Rainbow is a musical with a book by E.Y. Harburg and Fred Saidy, lyrics by Harburg, and music by Burton Lane, produced by Lee Sabinson. The original 1947 Broadway production ran for 725 performances, while a film version was released in 1968 and several revivals have followed.An elderly Irishman, Finian, moves to the southern United States with his daughter Sharon, to bury a stolen pot of gold near Fort Knox, in the mistaken belief that it will grow. Og, a leprechaun, follows them, desperate to recover his treasure before the loss of it turns him permanently human. Complications arise when a bigoted and corrupt U.S. Senator gets involved, and when wishes are made inadvertently over the hidden crock. The Irish-tinged music score includes gospel and R&B influences.
