Flatt and Scruggs

Lester Flatt and Earl Scruggs: Country music stars Flatt and Scruggs (who play themselves in seven episodes, 1963–68), are longtime friends of the Clampetts "back home" (Kimberling City, Missouri) who visit with the Clampetts when they are on tour in California. The duo had a number-one Billboard country single with the show's "The Ballad of Jed Clampett" (although the song is actually performed in the credits by Jerry Scoggins to Flatt and Scruggs' instrumental). Actress Joi Lansing played Flatt's wife, Gladys, in five episodes, 1963–68.
