"I Fought the Law" is a song written by Sonny Curtis of the Crickets and popularized by a remake by the Bobby Fuller Four, which went on to become a top-ten hit for the band in 1966 and was also recorded by the Clash in 1979.

Yes indeed you're correct. Another nice theory of mine ruined by actual evidence. I'm still hoping that the guy making the comment got it from The Clash though, just cause I'm biased towards them.
