Dame Ditty runs a successful school of singing with her star pupil Melody, much to the chagrin of the rival music teacher, Dr Discord (RAM), who has no pupils. When the Duke of Sterling and his daughter, Sophie, arrive in town, the rivalry between the two schools is brought into the open. A singing contest to be held at the local fair is suggested, but Dr Discord rigs the rules so only male singers are eligible. Discord coerces Benny, his handyman, to sing (very badly!) after threatening to throw Benny's mother out of her cottage. Dame Ditty has no male singer until Tommy Tucker arrives and is discovered to have a wonderful voice. Dirty work is afoot as Discord arranges with Mother Curseum to put a spell on Tommy, stealing his voice for Benny. But Melody and her friends enlist the help of Professor Wizo to reverse the spell and all comes right in the end.
