If this “perfect” edition isn’t the 1990 reissue edition with the uncensored Pastoral Symphony, I’d be much interested in making that one of my (admittedly very many) projects at some point in the near future.
By all means if you want to take that task and come up with something, please do so. As I’ve said before it amazes me how many versions of Song of the South and OT Star Wars we have. Yet almost nothing for Fantasia.
IMO this is the perfect Fantasia:
Blu Ray footage
Sunflower scenes from HD 35mm inserted in
LD Audio for most of the footage (including Deems where available)
DVD audio or 90s CD soundtrack audio for the Sunflower scenes where missing from LD audio
DVD audio dub for missing Deems voice
This basically restores Fantasia to the 1940 as much as possible using all the best available elements today.
