I was poking through some vintage sample packs from Zero-G (Datafile 3 in particular) and happened across a drum sample that sounds eerily similar to the drums found in Forest Moon from AFOT. The sample in Forest Moon has obviously been pitch-shifted/processed.
Datafile 3 came out in 1992 so it's not entirely out of the question to say they got the loop from there. However, the datafile series is also no longer available for purchase by Zero-G, as it contains samples in it taken from songs without the permission of the original copyright holders. For all we know they could have gotten it from anywhere.
Thought this was interesting and wanted to share.
