This is one of a series of arrangements written by Nelson Riddle for Ella Fitzgerald focusing on the Gershwin songbook. This arrangement of the classic Let's Call the Whole Thing Off  features a rubato introduction with vocalist and guitar before breaking into the melody in a medium swing setting. This chart includes only one trumpet with the part being just a soloist behind the vocals, though the part is largely written out. The melody, clever lyrics, and outstanding arrangement make this a chart you must have! Vocal Key: B-flat.
