Today in 1972, the first Broadway revival of Man of La Mancha opened at the Vivian Beaumont Theatre, where it ran for 140 performances. Man of La Mancha is a musical with a book by Dale Wasserman, lyrics by Joe Darion and music by Mitch Leigh. It is adapted from Wasserman's non-musical 1959 teleplay I, Don Quixote, which was in turn inspired by Miguel de Cervantes's seventeenth century masterpiece Don Quixote. It tells the story of the 'mad' knight, Don Quixote, as a play within a play, performed by Cervantes and his fellow prisoners as he awaits a hearing with the Spanish Inquisition.The original 1965 Broadway production ran for 2,328 performances and won five Tony Awards, including Best Musical. The musical has been revived four times on Broadway, becoming one of the most enduring works of musical theatre.
