"Recueil de pieces pour forte piano et violon pour Mme. la comtesse de Vauban" erroneously subtitled "Trios" (they are solos and duos), a collection of individual movements, some for piano alone, deserves the same doubts as the "Recueil d'Airs pour Mme. Vauban". Apart from drafts for two of Saint-Georges's , too many of these pieces seem incompatible with the composer's style. "Les Caquets" (The Gossips) a violin piece enthusiastically mentioned by some authors as typical of Saint-Georges's style, was composed in 1936 by the violinist Henri Casadesus. He also forged a spurious Handel viola concerto and the charming but equally spurious "Adelaide" concerto supposedly by the 10-year-old Mozart, which Casadesus himself later admitted having composed.
