Mozart was also Count Petofi's favorite composer (and probably a personal friend, too). There's a slightly hysterical scene during the Quentofi sequence of "Quentin" avidly listening to a Mozart recording.... I sometimes wonder whether this wasn't a tip of the hat to Mr. Norris' passion for the perky little Viennese and his compositions in the Christopher Isherwood novel "Mr. Norris Changes Trains."
