"Angel Eyes" is a song composed in 1946 by Matt Dennis, with lyrics by Earl Brent. It's a very popular jazz standard which has inspired many original interpretations. Several performers have recorded different versions of the song.
Ella Fitzgerald, who recorded "Angel Eyes" at least four times, named it as her all-time favorite song. In 1971, when Sinatra held what he intended to be his farewell concert (and the end to his show business career), he closed with "Angel Eyes". His retirement lasted only two years.
