The Use Your Illusion world tour saw Rose wearing "Charlie Don't Surf" t-shirts, emblazoned with Charles Manson's face - a move Rose claimed to be satirical of Manson, but which many considered to be inappropriate. In fact, "Charlie don't surf" is a quote from the movie Apocalypse Now. Lieutenant Colonel Bill Kilgore (played by Robert Duvall) wants to go surfing on a beach held by the Vietnamese. He orders his men to take the beach and explains that "Charlie [i.e. the Viet Cong] don't surf!" The phrase was also borrowed by The Clash, who used it as a song title on the album Sandinista!. I got this from Wikipedia so I cannot guarantee the accuracy, it's towards the bottom of the page-
