"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.
The song is best known for its remake that was released in November 1991 as a pop-house single subtitled "Stand by The JAMs", with verses featuring the vocals of American country music singer Tammy Wynette. This version was an international hit, reaching #2 on both the UK Singles Chart, and the U.S. dance charts, #11 on the U.S. Billboard Hot 100, and hitting #1 in 18 countries.
