You can find "We Are the World" on YouTube. There Johnston is, not far from Dionne Warwick as she sang at the five-minute mark of the song and next to Cher at the end, no more than 10 or 12 feet from song-leader Lionel Richie. You can see the kid in the white golf shirt with red stripes pumping his fist. He's pretty sure he wasn't singing along, Johnston said, because he didn't know the words.
