The cult of Jim Morrison grew posthumously, taking off in 1979 when Francis Ford Coppola used "The End" in the soundtrack for Apocalypse Now. Part of the cult of Jim was the coincidence of him dying at the same age as Brian, Jimi and Janis. The 27 link helped reinforce the idea that Jim had been special; that his death was fated; that there was something weird going on. The fact that Jim's girlfriend had died at the same age underlined the weirdness of the coincidence. This legend was familiar to everybody with an interest in popular music by 1994 when Kurt Cobain decided to join the club.
