The Emil Passani mystery

As I was searching various links in the Internet, I stumbled on the Berlioz Page of a fan, Mr.Matthew B. Tepper. Berliozeans should visit the site he's set with commendable erudition. On the article he devotes to the Requiem discography you will notice he mentions enthusiastically the Fournet recording. He apparently has inside information about the forces involved, which then should not be the "Orchestre et Chorale Emil Passani" but the Grand Orchestra of Radio-Paris and the Emile Passani Choir. Yet the French Columbia label of the LP reissue doesn't mention this. A mystery. Buyers of this transfer should not worry very much. But it is good to know. Truth to tell an "Emil Passani" orchestra has never been mentioned anywhere ever - as far as I can tell.
