Duke Ellington - Autumn Leaves

This has perhaps the greatest jazz violin of all time, by (sometimes trumpeter) Ray Nance.  Ozzie Bailey does a spectacular job on vocals in both French (written by poet Jacques Prévert) and English (by Johnny Mercer).  The music was composed by Joseph Kosma.

Fun fact: this was Yves Montand's signature song.  Just about everyone recorded this (Sinatra, Doris Day, Andy Williams, Miles Davis, Joan Baez, and Nat King Cole who recorded it in Japanese), but I love this version.
