The Barron Knights are a five-piece musical comedy group formed in Leighton Buzzard, Bedfordshire, England, in 1960. Members are Duke D'Mond (born Richard Palmer, February 25, 1945, Dunstable, Bedfordshire; vocals, guitar), Peter "P'nut" Langford (born April 10, 1943, Durham; vocals, guitar), Butch Baker (born Leslie John Baker, July 16, 1941, Amersham, Buckinghamshire; vocals, guitar), "Barron" Anthony Osmond (b. June 15, 1940, Abingdon, Berkshire; vocals, bass), and Dave Ballinger (b. January 17, 1941, Slough, Buckinghamshire; drums). They started out as a straight music group, then gained success doing parodies of the Merseybeat groups of the early '60s and never looked back, continuing to make fun of successive musical trends. Their first major hit was "Call Up the Groups" (number three, 1964), and they made the U.K. charts with a total of 13 singles through 1983, including "Pop! Go the Workers" (number five, 1965), "Merry Gentle Pops" (number nine, 1965), "Live in Trouble" (number seven, 1977), and "A Taste of Aggro" (number three, 1978). Their only U.S. chart entry came in 1979 with "The Topical Song," a parody of Supertramp's "The Logical Song."
