"Autumn Leaves" is one of my favorite pieces of music, especially this version! Here's a little history on it.
"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 and both as an instrumental and with a singer.
The film Autumn Leaves (1956) starring Joan Crawford featured the song, as sung by Nat King Cole over the title sequence. The French songwriter Serge Gainsbourg paid tribute to this song in his own song "La chanson de Prévert"
It is the corps song of the Bluecoats Drum and Bugle Corps.
The British Invasion band Manfred Mann released a rock version on their 1966 album, As Is.
Take care and God Bless!
