need help with ella song during malcom x

just watching part of the movie right now and just before malcom and betty get married they are sitting and an ella fitzgerald song is in the background.

it sounds as though it would be from the songbook series,but i can not place it.
The song is "Azure,' and you're correct, that's Ella singing.

"Azure" appears on the following albums (and perhaps others I missed) :

Ella Fitzgerald, "The Complete Ella Fitzgerald Song Books"
Ella Fitzgerald, "Best of the Duke Ellington Songbooks"
Ella Fitzgerald, "Ella at Duke's Place"
Ella Fitzgerald "Malcolm X [Original Soundtrack]"
Ella Fitzgerald "Sings the Duke Ellington Song Book"
