"Page Miss Glory" is a sort of spoof on a live-action film released a year earlier that starred Dick Powell, and that helps explain why this is a musical. Some of the usual suspects (i.e. Tex Avery) go uncredited, a condition that would change over time.
The story here revolves around a teenage bellhop, Abner (Tommy Bond, aka Butch from the Our Gang comedies, who also goes uncredited), who falls asleep while preparing to meet the titular beauty, or so it would seem, leading to an elaborate dream sequence that makes up the body of the film.
As with "At Your Service, Madame", which we showcased a while back, I'd never seen this in color when it aired in the 70's.
