I'll chime in with "The Circle Of Life" from the Lion King also.
When I finally got around to seeing it (I think on it's third time on tour to Seattle), at the end all I kept thinking was it would have been a lot better if they just did the opening "Circle of Life" number, lowered a screen to show the movie version, then raised the screen up at the end and do the reprise finale of "Circle of Life" again. I would have enjoyed it a lot more.
Xanadu! Can't cry on cue!
