Thanks. :)
That article is useful but I don't think it mentioned the 1985 VHS ANH at all, which is a major omission considering that was a new soundtrack.
Do you know if they remixed the sound for any of the other two films around that (mid 80s) or just ANH?
I read this claim that Star Wars on video was rare down until the 90s and that doesn't seem to fit with that article.
