"The Night Chicago Died" is a song by the British Group Paper Lace, that reached #1 on the hot 100 in 1974. The song is totally fictional, about a gun battle between Al Capone's mob and the police on the East side of Chicago. Not only did the battle never happen, there is no East Side of Chicago... just Lake Michigan. Anyway, it's a very cool song, a former #1, now mostly forgotten.
