Jerry Dengler (b. 29 Might 1955, Colorado Springs, Colorado, USA), Frank Gilligan (b. 2 November 1955, Queens, NY, USA) and Rick Henderson (b. 29 Might 1953, Beaumont, Tx, USA). Mason Dixon may be the brainchild of three graduates of Lamar School in Beaumont, Tx. They documented their combination of folk and nation for several little brands in the 80s and agreed upon with Capitol Information in 1988, launching two albums. Their most effective singles had been ‘3935 Western world End Avenue’, ‘When Karen Shows up Around’ and ‘Exemption To The Guideline’. Henderson was changed by Terry Casburn in 1989.
