After his military discharge he worked in a munitions company, based in
Shreveport, Louisiana for five years before being hired in October 1957 to promote
Starday Records country music catalog. When a marketing arrangement between Starday and
Mercury Records was terminated, Singleton was hired by Mercury to do promotional work. He rose in the company to become a record producer and executive in Mercury's Nashville office. In 1960, he achieved his first
hit single,
Brook Benton's
recording of "
The Boll Weevil Song", which became a #2
single on the
Billboard Hot 100 chart the following year. Singleton spent nine years at Mercury and its sister label,
Smash Records, during which he was involved in producing many hit records, including
Leroy Van Dyke's "
Walk On By"; "
Ahab the Arab" by
Ray Stevens; and "
Wooden Heart" by
Joe Dowell. He was responsible for convincing
Roger Miller to sign with Smash Records, where he would have most of his hits of the '60s. Singleton also acted as producer for such artists as
Jerry Lee Lewis,
Roger Miller,
Charlie Rich,
Dave Dudley,
Brook Benton, and
Orion (singer). In 1962, Singleton bought the master recording of "
Hey Paula" by Jill and Ray, originally released on LeCam Records. He changed their names to
Paul & Paula and issued the song on Mercury's sister label,
Philips Records. The song spent three weeks at number one on the
Billboard Hot 100. By 1966, Singleton was vice-president of Mercury, but resigned to form several music labels, including SSS International and
Plantation Records. In 1972 the Flatlanders traveled from Lubbock to Nashville to record with Clark for Singleton's Plantation label. Singleton and Clark worked closely together in later years, finding and recording undiscovered talent which Clark produced for Singleton's Plantation label, such as Ron Daisley and The County Fair from Long Island, New York, consisting of Ron Daisley on guitar and vocals, Bill Black on Bass, Daryl Brooke on pedal steel guitar, John Backerty on electric guitar, and Paul Gelsomine on drums. ==Private life==
