In the late sixties, of course, LSD was on everyone's mind. That was my era. I was in my teens at the time. I'd been interested in acid ever since I'd first seen Timothy Leary in a news item on TV, since seeing a picture of the Grateful Dead in the Sunday Mirror (they looked so cool, with their granny glasses and long hair), since hearing Lucy In The Sky With Diamonds from the Sergeant Pepper album down at Robert Russell's place. Lucy In The Sky With Diamonds was, I was reliably informed by Robert Russell - who was an expert on such things - an elliptical reference to the LSD experience.
