Ella Fitzgerald recorded this song many times in her career, and we offer you what we feel to be her finest version, from the 1960 Billy May collaboration album "Sings the Harold Arlen Songbook". This chart is just great all the way through, from the almost Phrygian opening into the relatively reserved first chorus, the blasting band chorus (including the fully written out Tenor solo), Ellas more fluid second vocal chorus (also written out in full), the implied repeat to fade and the punch finish. This chart is simply a must have for any big band library. The vocal key is Bb.
