I think the "Celebrate the Future" Music is the track from the Official Album WDW 1999. Can anyone verify this? (sorry if this was already posted in the past)
I am afraid we cannot confirm this due to the fact that we would be "reverse engineering" trade secrets of Disney, and, thus, be in severe legal jeopardy, at least according to one legal "wizzard" who seems to spout all sorts of nonsense.
But, as to your specific question, I am not sure if it is the same track. At a minimum, it would have to be edited from the original run time. I have what was supposed to be copies of the tracks actually used for the shows, but I've never done anything with them to confirm if they are the real deal or fake tracks someone thought they could trade with. Perhaps I can see if there is a YouTube version of the actual track and do a quick comparison.
