Isn't it a wonderful tune? I especially dig an obscure version with Ben Sluijs on saxophone and Nathalie Loriers on piano.
Anyway, it's a typical standard, but the chord changes are especially nice with the presence of the Bb7 (#11 to be precise). One of Duke Ellington's favorite chords and it brings the Melodic Minor flavor into the major scale mix.
As always, you can find the song for free in MGU-file-form here. When you open it, it will look for the style I made, but you can substitute it with any other style you like.
The song was made with a Jazzstylezz style you can find in the Standards Pack 1
