I’ve mentioned a few times about last August when I went to the D23 expo I attented a film restoration presentation. One if the things I asked the guy was about the original “fantasound” soundtrack with the Deems Taylor narration.
The guy said that he wants nothing more than to be able to present the film with that original narration, but that they simply don’t have the original stereo tracks or the master tapes for the deems Taylor narration. That at some point before anyone he knows started working there, they were lost or destroyed somehow. He said it makes him extremely sad and that even though Corey Burton is a fantastically talented voice-over actor, he wishes they could track down that original narration in any kind of usable, high quality form. He did say they’ve been trying to track it down for years, with no luck, but that it makes it considerably harder when the powers that be don’t seem to care as much about it as the people restoring it and won’t fund a wild goose chase.

He seemed throughout the presentation to have a certain disdain for Disney executives and their lack of appreciation for the integrity of their own cinematic history.

To quote him directly “if we had it, we would use it. Unfortunately we just don’t right now”
