This standard could possibly be the link between show tunes and what came to be known as jazz standards. It stands out in every regard and is totally time-honored among all jazz musicians. The song is loved less for the downbeat-avoiding melody that Gershwin wrote than the tune itself as a vehicle for endless hours of improvisation and fun. The chords have become so famous that they’ve eclipsed the composition itself. Try playing it here as a Samba!
