Yeah, my audio track is from the Region 2 GOUT DVD and is 100% castilian spanish, with no latino american spanish audio mix in it.
I think it shouldn't be difficult to recreate the music effect with the soundtrack... Even the isolated track of many star wars fan projects of this forum has that particular segment.
About the VHS track if you have any clues in how to syncronized it, just let me know... but anyway I'll make new attempts, wrinting about all of this story it's rising up my motivation again to make new tries. lol
