Keith Richards came up with a perfect explanation for how it sounds: sheer sexual exhaustion. “Three thousand screaming chicks could just wail you out of the whole place. Just looking at the crowd, you could see them dragging the chicks out, sweating, screaming, convulsing.” All those years of screamers took their toll—especially since the Beatles were way ahead of the Stones when it came to on-the-road girlie action. “They talk about us, but the Beatles, those chicks wore those guys out. They stopped touring in 1966—they were done already. They were ready to go to India and shit.”
