 This lunch ended with Auric and Tailleferre taking the score of Thomson's "The Mother of Us All", which Thomson had given as a gift, turning it upside down on the piano and having Poulenc singing all of the roles (including Susan B. Anthony) in nonsense English syllables which were supposedly an imitation of Gertrude Stein's Libretto while Tailleferre and Auric improvised a four-hands version of Thomson's score.After this memorable day, Tailleferre invited the couple to her home in Grasse to spend two months while she was writing her ballet "Paris-Magie" and her opera "Il était Un Petit Navire".She wrote two-piano versions of both works and gave them to the duo as a gift.
