A flash of Las Vegas police motorcycle headlights illuminates Bono from behind as he ambles forward, his voice and arms rising in unison as a sudden burst of color swallows the darkness like neon jaws clamping shut. He sings of scaling the highest of mountains from the depths of downtown, his wardrobe as black as the shadowy alley down which he strolls. A scene from U2's iconic 'I Still Haven't Found What I'm Looking For' video filmed on Fremont Street on April 12, 1987.
