Big Thunder Mountain Railroad, Audio Recordings?

[Braden Lucier]

I'm having trouble to find a lot of sound effects that was used on Big Thunder Mountain Railroad at Walt Disney Worlds Magic Kingdom, it's a part where the track goes to the dusty mining town of Tumbleweed, especially if you ride the Walt Disney World Railroad while leaving Frontierland Station, you can see the dusty mining town of Tumbleweed, with sounds like Two Donkeys Braying, a Goat Bleating, Pigs Oinking, etc.

My question is, How do I find these recordings in High Quality from the Big Thunder Mountain Railroad 1980 Version, does anyone know?
