The groundbreaking 1947 musical Finian’s Rainbow follows an Irishman who steals a feisty leprechaun’s pot of gold and escapes with his daughter, Sharon, to Missitucky, a mythical region in the United States that is part of the Jim Crow South. The daughter and the sprite each find romance with others, but also encounter bigotry, economic disparity and cultural injustice. The score is spiked with such popular show tunes as “Old Devil Moon,” “How Are Things in Glocca Morra?” and “Look to the Rainbow,” plus spicy comic and satiric songs such as “When I’m Not Near the Girl I Love,” and “When the Idle Poor Become the Idle Rich.”
