KLF - justified and ancient, 1991

"The KLF—King Boy D (Bill Drummond) and Rockman Rock (Jimmy Cauty)—began working together in 1987 as the Justified Ancients of Mu Mu (the JAMs). The song title "Justified & Ancient" refers to this pseudonym. The JAMs took their name from a fictional subversive cult from the 1970s conspiratorial novels The Illuminatus! Trilogy."
