Charles Sheffield (aka Mad Dog) was an early-'60s R&B singer from Lake Charles, LA, noted for the local/regional hit "It's Your Voodoo Working," which is acclaimed more now than when it debuted on Excello Records in 1961. Sheffield cut "It's Your Voodoo Working" at Crowley Studios, which is most noted for blues and R&B recordings. He wrote and recorded 'Voodoo' along with about five other songs which failed to cause a ripple, and then soured on the business and disappeared from sight.

Charles ‘Mad Dog’ Sheffield, cut 'It's Your Voodoo Working' for J. D. Miller at his Crowley, Louisiana studio in 1961 and released on Nashville’s Excello Records, as were many of Miller’s productions.
Sheffield was a blues singer originally from the Beaumont, Texas area on the Gulf Coast, who started off recording as Mad Dog Sheffield in 1957. Backed by the Clarence Garlow Orchestra, he cut a tune called “Mad Dog” for the Goldband label (#1045) out of Lake Charles. Louisiana. Eddie Shuler, owner of Goldband, then leased the single to Hollywood Records (#1079) that year to no avail. Around 1959, the singer started recording with Miller, who initially issued two singles on his in-house Rocko label credited to Charles Sheffield. Then, Miller got Excello to put out “It’s Your Voodoo Working” b/w the fast chuggin’ “Rock ‘N Roll Train”, and a follow-up, “I Would Be a Sinner” b/w “The Kangaroo”; but, despite their excellent quality, both records, like Sheffield’s previous releases, failed to catch on. As far as I know, he only had two other singles, both credited to ‘Prince Charles’ and recorded for ‘The Crazy Cajun’, Huey Meaux, who issued them on his Teardrop and Jetstream labels respectively between 1962 and 1965.
