Ramsey Emmanuel Lewis, Jr. (born May 27, 1935 in Chicago, Illinois) is an American jazz and pop pianist and keyboardist. He formed the Ramsey Lewis Trio in 1956 with Eldee Young and Isaac Holt. They started as primarily a jazz unit but after their hit, "The In Crowd", in 1965 (the single reached fifth place on the pop charts, and the album second place) the trio concentrated more and more on pop material. Young and Holt left in 1966 to form the Young-Holt Trio and were replaced by Cleveland Eaton and Maurice White.
