Jimmy Castor is known most for the boogaloo crossover hit "Hey Leroy, Your Mama's Calling You" (1966), Top Ten pop single "Troglodyte (Cave Man)" (1972), and the crucial hip-hop building block "It's Just Begun" (also 1972), among other oft-sampled material. While animated funk was the musician's specialty, at least from a commercial perspective, Castor was no mere novelty act, with his roots in doo wop and jazz visible throughout his career. Moreover, John Pruitt, his songwriting/production partner, called him "the Everything Man," a nickname with merit. In addition to playing saxophone, his primary instrument, Castor wrote, arranged, produced, sang, played keyboards, mastered Latin percussion, and was a bandleader, most notably helming the Jimmy Castor Bunch throughout the '70s. His album discography is highlighted by It's Just Begun, which reached number 27 on Billboard's LP chart in 1972, and ends with a solo set issued just over a decade later.
