Gala GL 100.747 (barcode 8712177046133), the issue this archive holds a rip of (rips/rip-6581); its back cover and booklet p.2 give the 1973 Dervaux cast as "Jean Alain Vanzo / Frere Boniface Robert Massard / Le Prieur Jules Bastin / Le Moine poete Jean Dupouy / Le Moine peintre Claude Meloni / Le Moine musicien Yves Bisson / Le Moine sculpteur Pierre Thau / Deux Anges Christiane Issartel, Jeanine Collard. Orchestre Philharmonique et Choeurs de l ORTF. Conductor: Pierre Dervaux. Paris, December 15, 1973." Corroborated by the Stanford University Libraries catalogue record for Gala GL 100.747, https://searchworks.stanford.edu/view/10624652 (Vanzo, Massard, Bastin; Orchestre philharmonique de l ORTF; Maitrise et Choeurs de l ORTF; Dervaux; Dec. 15, 1973, Paris). findopera 3032 had been carrying a verbatim copy of the cast of 3032 s sibling 3031, the 1978 Monte-Carlo recording under Roger Boutry (Vanzo, Bastin, Vento, Raffalli, Fremeau, Carey, Doumene, Casini) -- which is the cast that issue is credited with, so 3031 is the one that was right. Sang one of the Deux Anges.
