“Autumn Leaves is a much-recorded popular song. Originally it was a 1945 French song “Les feuilles mortes” (literally “The Dead Leaves”) with music by Hungarian-French composer Joseph Kosma and lyrics by poet Jacques Prévert, and the Hungarian title is “Hulló levelek” (Falling Leaves). Yves Montand (with Irène Joachim) introduced “Les feuilles mortes” in 1946 in the film Les Portes de la Nuit.”
