I just found out this movie existed. I know it’s a musical, but is it a jukebox musical (all preexisting songs), or is it new numbers and the somewhat-related song they got so they’d have a recognizable title? It’ll be interesting to find out.
I strongly suspect that the “Dance TV” alluded to in the summary is a stand-in for MTV.
There’s a tendency for the family comedies Disney made in the 50s-70s to blend together, unless they reached you early enough to trigger nostalgia. At this point, it’s hard to say if that’s the classics rising to the top, or one generation passing their nostalgia to the next.
This is not one of the well-known ones. At least, I only learned about it by finding it on a shelf. It stars Dean Jones, but so does almost every movie Disney made back then. Disney’s stable of reliable actors reminds me these days of the contract system of the Golden Age of Cinema, where actors contracted to do so many movies of whatever kind they were assigned to with the same studio before they were free to leave or renew their contract, which also created a kind of repertory effect.
