 The artistic salon resumed activity as before, introducing to R-26 singer Josephine Baker, a mutual friend of Le Corbusier and Tranchant.Django Reinhardt and Stéphane Grappelli continued to favor R-26 as an informal rehearsal space for the Quintette du Hot Club de France, often improvising with other members of the salon.In 1947, in honor of ten years spent at R-26 as guests of the Perrier family, Reinhardt and Grappelli composed the song "R. vingt-six", to be used as an anthem among the salon's members.
