From one Fantasia diehard to another, welcome to the site.đź‘Ť
So, for this, you’ll need a 35mm magnetic stereo print of the '82/'85 releases and a facility capable of capturing the sound from those prints to access any of those recordings; the interstitial commentaries from those dubs have, unfortunately, never been released to the public in any other form.
I do know someone who has a print of one of those digital stereo reissues and, color fading aside, claims it’s in pristine physical condition. They’ve offered to loan it to me before for preservation, so once I cross off a few other to-dos from my list, I may have that arranged for another project I still have brewing. I’ll keep you and anybody else interested posted.
