"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 Joseph Kosma and lyrics by poet Jacques Prévert.
Yves Montand (with Irène Joachim) introduced "Les feuilles mortes" in 1946 in the film Les Portes de la Nuit.
The American songwriter Johnny Mercer wrote English lyrics in 1947 and Jo Stafford was among the first to perform this version.
Autumn Leaves became a pop standard and a jazz standard in both languages, both as an instrumental and with a singer.
