Close Encounters of the Third Kind sheet music (Uncle Buck?)

[rhizome]

Hi! I do not have a tuba so this is not a forum on which I would normally hangout. However, I'm trying to contact a user named "Uncle Buck" who posted five years ago that he had the actual tuba sheet music for Close Encounters of the Third Kind. He said it was given to him by Jim Self at Octubafest 1990 at BYU. I had seen that movie when I was little and when I read recently that the voice of the mothership was actually a tuba I was blown away and have become a little tuba-obsessed. I mean, I'm not sculpting tubas out of my mashed potatoes or anything, but I have been learning more and trying to understand what Jim Self was given to work with.

I've been looking for the sheet music, but I'm coming up only with transcriptions. The best appears to be Mark DeSimone's (https://www.youtube.com/watch?v=g8_7r45wl2s) which changes time signature liberally to make it easier to read. There's a doctoral dissertation on the tuba I found ("Of Sharks and Spaceships" by Stephen Turner, https://digitalscholarship.unlv.edu/the ... ions/3053/)
which uses handmade transcriptions from the film, but also notes that it was "spliced and sutured" from the studio recording by Jim Self.

So, what was the sheet music Jim Self was given by John Williams? Google only returns that Uncle Buck on this forum once said he might have such a thing hidden in a box in his basement.

Any help would be appreciated.
