Not sure how wrong Ed was here, we're getting a remastered version of something we have had for years. Welcome, but not as dramatic as the unheard Rainbow show.
Just remastered?
Or newly mixed from a multitrack tape?

The point is that Ed was giving every reason why these shows are not to be released.
And all reasons were valid points.
But hopefully there are still some persons with the will to make it possible and spending time and money (they doesn't work for free do they?) to locate the stuff.
Regarding the 1992 september broadcast from Nimes.
I understantd that our beloved uncle ED is not remembering this, 30 years after the facts in a country that awarded him with a gold record by a disco band covering Dire Straits.
Again he gave thoeries about possible reasons for the tape to be lost.
First I remember watching the show again few years after on the public TV channel.
As everything aired by public TV in France is by law stored for archival pupose by INA I know that a backup copy exists.
And to my know they are serious with this.
Second although I have no proof, I would be surprised that Canal+ did not store the show in their own archive.
Third Canal+ and UMG are both subsidiaries of Vivendi, so despite being different entities they are owned by the same persons/companies.
So if UMG was willing to release or use part of this show these would be positive reasons to make it possible.
