Meredith Willson's The Music Man The Wonderful World of Disney : Season 5 Episode 23

Confidence man Harold Hill arrives at staid River City intending to cheat the community with his standard scam of offering to equip and train a boy's marching band, then skip town with the money since he has no music skill anyway. Things go awry when he falls for a librarian he tries to divert from exposing him while he inadvertently enriches the town with a love of music.
