In 1987, Bill Drummond and Jimmy Cauty's collaborations began in London, England. They assumed alter egos - King Boy D and Rockman Rock respectively - and they adopted the name The Justified Ancients of Mu Mu (The JAMs), after the fictional conspiratorial group "The Justified Ancients of Mummu" from The Illuminatus! Trilogy. In those novels, the JAMs are what the Illuminati (a political organisation which seeks to impose order and control upon society) call a group of Discordians who have infiltrated the Illuminati in order to feed them false information.
