Okay so this has been killing me for years... Long long ago When the Disney channel used to play movies from the "vault" (very old Disney classics) I was awake to see a movie that I really enjoyed but fell asleep halfway through. The movie was about a singing group that was to perform at Disneyland that ran into some issues along the way. It is a very old movie (judging by the attractions like skyway still being there). In one portion of the film, the female band member begins singing on the second floor of innovations overlooking tomorrowland.
If anyone has seen anything similar please let me kno I wanna watch it :)
