He had this idea. It was kind of a virologist idea. He believed that you could cure racism and hate... literally cure it, by injecting music and love into people's lives. When he was scheduled to perform at a peace rally, a gunman came to his house and shot him down. Two days later he walked out on that stage and sang. When they asked him why - He said, "The people, who were trying to make this world worse... are not taking a day off. How can I? Light up the darkness."
