Keith Richards, Anita Pallenberg, Mick Jagger, Marianne Faithful, and Gram Parsons at Stonehenge, on acid. Photographs by Michael Cooper 1968.
"We started off very early from some club in South Kensington; set off about two or three in the morning in Ketih's Bentley. And we walked across a sort of track to Stonehenge in order to approach it in a properly reverent manner, and watched the dawn come up there. And we were all gibbering with acid." --from Keith Richards, Life
