By this time, Phillips had built a new state-of-the-art studio at 639 Madison Avenue in Memphis, thus abandoning the old Union Avenue studio where Phillips had recorded B. B. King, Howlin' Wolf, Elvis Presley, Carl Perkins, Lewis, Johnny Cash, and others. It was at the new Madison Avenue studio that Lewis recorded his only hit during this period, which was a cover of Ray Charles' "What'd I Say" in 1961. Another recording of Lewis playing an instrumental boogie arrangement of the Glenn Miller Orchestra favorite "In the Mood," was issued by Sun under the pseudonym of "The Hawk," but disc jockeys quickly figured out the distinctive piano style, and this gambit failed.

Lewis's Sun recording contract ended in 1963 and he joined Smash Records, where he made a number of rock recordings that did not further his career.
