I used to have a CD with Fantasmic! soundtrack and the Main Street Electrical Parade. We must of got it when I was young and I loved that CD. I can't seem to find it...
For anyone curious, here's what one of the folders looks like from my Haunted Mansion Unauthorized 36th Anniversary Edition (Specifically Folder 2)
Although I do not own the Pirates of the Carribean Unauthorized Anniversary Collection, I can assume that it would be set up much like this. Different folders containing different materials, like Folder 2 (As shown) contains nearly all the sound clips from the Haunted Mansion, while Folder 3 deals with foreign Haunted Mansions and Haunted Mansion Holiday, Folder 4 contains misc. sound clips like unused Ballroom Organ music, early, alternate, or different versions of Grim Grinning Ghosts, etc. If I did have possession of the PotC Collection, I could only guess it would be set up like that; different folders covering different materials and such.
The more I talk about it, the more envious I am to own it :p
