"Justified & Ancient" is a song by British band the KLF (Bill Drummond and Jimmy Cauty) which featured on their 1991 album The White Room but with origins dating back to the duo's debut album, 1987 (What the Fuck Is Going On?). Despite its success, "Justified & Ancient (Stand by the JAMs)" was the final release by the KLF through retail channels as well the second-to-last altogether release from the KLF (the last release being the mail-order only "3 a.m. Eternal") before Drummond and Cauty quit the music business and retired the KLF name.
