As recorded on the album The Jazz Soul of Porgy and Bess (featuring the Bill Potts Big Band), this chart swings hard, but it isn't hard to play. Bill arranged this in a wonderful contrapuntal fashion. He also chose to feature alto, tenor, trumpet, piano and drum solos. This arrangement should be in all big band books. 5-5-5-4 (can be played by only 8 brass).
