Changes

''The Music Man'' is the only Broadway musical to feature a barbershop quartet. An integral part of the plot, they are not initially a quartet, but four members of the school board who are always sniping and bickering. As soon as Harold Hill coaxes them to sing one single, perfect chord together, they are thrilled with the sound they have produced. They are now, literally, in harmony. Harold Hill predicts, correctly, that henceforth they will never be seen out of each other's company.

In 1962, ''The Music Man'' was translated into an unusually faithful screen adaptation, starring Robert Preston and Shirley Jones and directed by Morton da Costa, mostly from the original Broadway production.<ref name=ibdb/><ref>[http://www.imdb.com/title/tt0056262/combined The Music Man], Internet Movie Database</ref>
