Hi,
I hope I can post this. It's not something that's available for sale. I found it on a website called Lost Epcot, that's been online for a good 8 years!
It's the full (17:42) audio to the original 1983 Journey Into Imagination ride at Epcot. This audio is pure magic. So many beautiful, warm sounds. Check it out:
