Info Wanted: Original Jabba the Hutt Scene -- Help IDing sources in this reconstruction.

Just as the title says I’m looking for what sources were used to reconstruct this scene I have found on various interweb tube outlets.

Hints or Links to any Quality sources are appreciated.

Surely “A New Hope”'s SE featurette (https://www.youtube.com/watch?v=zB4woJeligY). I think I specifically saw that edit you posted in the fan documentary “Star Wars Begins” (http://fanedit.org/ifdb/component/content/article/85-fanedit-listings/documentary-review/416-star-wars-begins)
There probably are officially released sources, but I doubt they’re more than SD, unfortunately.
