Big Jay McNeely was an American rhythm and blues saxophonist known for his energetic, honking playing style. Emerging in the post-World War II era, McNeely was a significant figure in the development and popularity of "jump blues," a type of up-tempo blues featuring brass instruments. His most influential work, the 1949 single "Deacon's Hop," topped the Billboard R&B chart, exemplifying his signature sound. McNeely's flamboyant performances, often playing on his back or while walking through the audience, greatly influenced future rock and roll stage acts.
