Jerry Lee left Sun in 1963, but, like Elvis, returned often. By the mid-1970s, the studio was run by Sam Phillips' son, Knox, who produced one of the era's biggest hits, the Amazing Rhythm Aces' ":Third Rate Romance.": Like his father, Knox intuitively understood how to produce Jerry Lee Lewis, allowing him free rein to plunder his subconscious for half-forgotten songs and reimagine them as Jerry Lee Lewis songs, just as he d done with ":Whole Lotta Shakin;": twenty years earlier.
