Recording as Cledus Maggard & the Citizen's Band, Huguely - working at the time for Leslie Advertising in Greenville, South Carolina - enjoyed his one and only hit in 1976 with "The White Knight." Released during the wave of popularity of the citizens' band radio, the song is about a semitrailer truck driver victimized by a Georgia highway patrolman's speed trap. He chose the name "Cledus" after his mother's name Cleta.
"The White Knight" reached No. 1 on the Billboard magazineHot Country Singles chart in February 1976, and was his only hit to reach that chart's Top 40. Following the success of this record, Huguely most notably was a producer on the 1980s television series "Magnum, P.I." In the 1990s, he was a writer and producer, known for Jason Goes to Hell: The Final Friday (1993), Street Justice (1991) and Bandit: Bandit's Silver Angel (1994).
