Question: Who was the producer for the group The Shelor Family?

"O-o-h Child" is a 1970 single recorded by Chicago soul family group the Five Stairsteps and released on the Buddah label.  Previously, the Five Stairsteps had had peripheral success recording in Chicago with Curtis Mayfield: when Mayfield's workload precluded his continuing to work with the group they were reassigned to Stan Vincent, an in-house producer for Buddah Records, who had recently scored a Top Ten hit with the Lou Christie single "I'm Gonna Make You Mine".  Vincent wrote the song for his son, Chuck.  The Five Stairsteps' debut collaboration with Vincent was originally formatted with the group's rendition of "Dear Prudence" as the A-side with Vincent's original composition "O-o-h Child" as B-side.  However, "O-o-h Child" broke out in the key markets of Philadelphia and Detroit to rise as high as #8 on the "Billboard" Hot 100 in the summer of 1970.  The track's R&B chart impact was more muted with a #14 peak, although "O-o-h Child" is now regarded as a "soft soul" classic.  "Billboard" ranked the record as the No. 21 song of 1970. <SEP> The Bristol Sessions are considered the "Big Bang" of modern country music.  Bristol was one of the stops on a two-month, $60,000 trip that took Peer through several major southern cities and yielded important recordings of blues, ragtime, gospel, ballads, topical songs, and string bands.  The Bristol Sessions marked the commercial debuts of Jimmie Rodgers and the Carter Family.  As a result of the influence of these recording sessions, Bristol has been called the "birthplace of country music".  Since 2014, the town has been home to the Birthplace of Country Music Museum.  They were held in 1927 in Bristol, Tennessee by Victor Talking Machine Company producer Ralph Peer. <SEP> The Shelor Family (also known as Dad Blackard’s Moonshiners) was an American folk music group formed in Meadows of Dan, Virginia in the 1920s.  Their music, which was recorded during the Bristol sessions in 1927, had a profound impact on country and bluegrass music.  The original family band included Joe Blackard (banjo, vocals), his daughter Clarice (piano, vocals), Jesse Shelor (fiddle, vocals) and Pyrhus Shelor (fiddle), and later resurfaced on an album of field recordings arranged in 1975. <SEP> Chuan Ratanarak (Thai: ชวน รัตนรักษ์) (1920–1993) was a self-made Thai businessman who built one of the largest and most powerful business empires in Thailand.  Starting with nothing, Chuan was one of the legendary generation of Chinese merchants in Thailand to achieve success in one generation.  By the time of his death in August 1993, age 73, Chuan was at the head of one of the three dominant business families in Thailand - the others being the Sophonpanich family and the Lamsam family - and the business group Chuan had created, the Ratanarak Group, included Thailand’s most successful terrestrial broadcaster, a major retail banking and insurance group and the country’s second largest cement producer.  Comparing Thai and US entrepreneurs, Professor Krishnamra, head of the Sasin Business School at Thailand’s Chulalongkorn University, has said “given the size of the market and the stage of development, Chuan as an entrepreneur was comparable to the Vanderbilts or Rockefellers”.  Chuan is the father of Krit Ratanarak and the grandfather of Chachchon Ratanarak.
