"if he went again to Serge Panine"

Serge Panine was a bestselling novel by Georges Ohnet (1848-1918), adapted into a play which was not a critical success. Swann, again, is indulging Odette's taste for more popularist work. Olivier Métra (1830-1889) was a composer and conductor. His music was extremely popular, and he conducted at the Folies Bergère. Reynaldo Hahn, a composer who was Proust's close friend and lover, featured some of Métra's waltzes in his own work.
