Nat Adderley composed One For Daddy-O as a tribute to Holmes "Daddy-O" Daylie, an influential Chicago radio disc jockey who championed jazz during an era when radio was the primary medium for music discovery. The tune is a twelve-bar minor blues with a swinging, understated melody that balances accessibility with improvisational depth. It first appeared on the landmark 1958 Blue Note album Somethin' Else, led by Cannonball Adderley and featuring Miles Davis on trumpet, Hank Jones on piano, Sam Jones on bass, and Art Blakey on drums. The session was recorded on March 9, 1958, during a period when Cannonball was a member of Miles Davis's First Great Quintet, making the album a notable document of their collaboration. The composition exemplifies Nat Adderley's gift for crafting blues-rooted material that is direct and unpretentious yet musically substantial enough to support diverse soloing approaches. Despite appearing on one of the most celebrated albums in the Blue Note catalog, One For Daddy-O has remained a moderately performed tune rather than a universal standard. Only a handful of documented recordings exist beyond the original, including two live performances by the Cannonball Adderley Quintet in Europe in November 1960, one at Amsterdam's Concertgebouw and another in Sweden two days later, both featuring Nat Adderley on cornet alongside Victor Feldman, Sam Jones, and Louis Hayes.
