Guy Ropartz, who had led a concert performance of the third act of "Guercoeur" at Nancy in February 1908, reconstructed from memory the orchestration of the acts that had been lost in the fire. The Paris Opéra gave the work a belated world premiere in 1931. (A complete recording of "Guercœur" was released by EMI Angel/Pathé Marconi in 1990. It features Hildegard Behrens, Nadine Denize, José van Dam, and Gary Lakes, with the Orchestre du Capitole de Toulouse conducted by Michel Plasson.)
