No, this print is the familiar shorter cut of the film. There is no doubt in my mind that Disney has the Deems Taylor audio from that cut. I cannot conceive of any way they’d have lost it between the 1990 restoration and the 2000 restoration. What they don’t have is soundtrack for the scenes that were cut after the 1940 roadshow release, the scenes that were only reinstated to the film in 2000. That’s why they redubbed all the scenes, because if they only dubbed the new scenes, it would have been too jarring.
As I said before, the fact that Disney had to redub scenes for which audio exists just to reinstate scenes for which they didn’t have audio, shows that they should have just left those scenes out of the main film and presented them as a bonus feature, with an explicit disclaimer that they had to be dubbed because the original audio was missing. (Or at least found someone who sounded more like Deems Taylor, so they could have used the original audio for the scenes for which they had it, and the dubbed additional footage would have blended in better…)
