Nat Adderley

Nathaniel Carlyle Adderley (November 25, 1931 – January 2, 2000) was an American jazz trumpeter. He was the younger brother of saxophonist Julian "Cannonball" Adderley, whom he supported and played with for many years.

Adderley's composition "Work Song" (1960) is a jazz standard, and also became a success on the pop charts after singer Oscar Brown Jr. wrote lyrics for it. Provided by Wikipedia
