Basically it was a riff that we would do at sound-checks. Axl came up with a couple of lines at the beginning. And... I went in a peace march, when I was a little kid, with my mom. I was like four years old. For Martin Luther King. And that's when: "Did you wear the black arm band when they shot the man who said: 'Peace could last forever'?" It's just true-life experiences, really.
