Cotton Candy

From the tepid 1978 made-for-tv movie of the same name. Directed by Ron Howard, the plot concerns George Smalley (Charles Martin Smith) starting a high school band with a bubble gum sound that goes up against the obligatory evil hard rock band in the also obligatory "Battle of the Bands." Ron Howard's brother, Clint (who also co-wrote the movie), plays Corky Macpherson, the band's manager.
