I was visiting Epcot on Thursday with some friends, and we made our way over to the Imagination pavilion to watch Captain EO. Beforehand, we visited the restrooms at the far end of the pavilion, and it sounded like the original Imagination music loop was playing in there. At the time I visited, "Makin' Memories" from the Magic Journeys pre-show was playing in a very 80s synthesized style. Just to be clear, the exterior BGM was still the "normal" current Imagination music.
