Man of La Mancha is a musical inspired by Miguel de Cervantes' Don Quixote. Designed as a play within a play, Cervantes tells the story the mad knight Don Quixote, while in prison awaiting a hearing with the Spanish Inquisition.
The musical was developed at the Goodspeed Opera House in Connecticut (where over forty years later Emmet Otter's Jug-Band Christmas would debut), and the musical made its bow on Broadway in 1965, winning five Tony Awards and running for six years. It has seen numerous revivals, and has been a staple of high school and community theatre productions across the country. Its signature song, "The Impossible Dream", has become a standard in the American songbook.
- The show was parodied during Season 37 of Sesame Street with "Man of La Muncha" where a child named Johnny sings about eating an "incredible meal" with his family.
