@hightor,
Yeah, I caught this notice too. Cream was my first rock concert ever, when their tour hit Vancouver in summer, 1968. We were very familiar with their music, of course. When they came out on stage, Clapton was holding a bottle of Coca Cola and said, "We always bring a little coke up on stage with us", which got the desired audience response. The main thing I recall of that evening (yes, we were very stoned) was the massing of young people like us, all in hippy mode. I remember thinking, "Jesus, we could take over the world" (which has turned out to be less agreeable than my stoned youthful optimism suggested).
Many years later, a hometown hippy buddy, there with us that evening, toured with Jack Bruce as a vocalist. Two or three years ago, he sent me a link to a Brit TV video from the early 60s where Ginger was playing with some group of guys as early Brit go-go dancers swung their arms and asses and third tier Brit comics ran about the set in monkey costumes. We all have to start somewhere.
