I’m always interested in the origins of things: the why. So for the selection “The Impossible Dream” (titled “The Quest” in the actual script) from Man of La Mancha that I’ve sung with my own choir I wanted to know why on earth a popular Broadway show had been made from a 400-year-old, 700-page novel, Miguel de Cervantes’ Don Quixote. Doesn’t sound all that likely, does it? And yet it happened. (There are lots of other unlikely origins for Broadway musicals, though—Kiss Me, Kate is based on Shakespeare’s The Taming of the Shrew.)
