I don't remember that in the 60's, but then I was happy to watch the girls in mini-skits...haha. I thought it was early 70's, but could have been late 60's that chant started. That was all in my teens and now 68 and could be wrong, but not going to bother to google. I'll take your word for it.
A small factoid about my mid-60's experience: I used to drive my friends nuts when riding in my car because I loved the early 60's girl groups (Shirelles, Chiffons, et al) and Golden Oldies of the 50's and then fell in love with Motown. I can't remember how many shotgun (remember that?) riders would ask me to turn off Smokey, Supremes, Temps, Otis Redding, Aretha, etc.
Then there was the competition between Beatles and Stones fans. Of course, I was a Stones fan because the Beatles were doing bubble-gum pop when the Stone were doing covers of Muddy Waters, and other Chess artists. I still listen those classics of that era, especially since most have been re-mastered and re-mixed.
If you're a Stones fan, the 2 disc "GRR!" compilation is the best they've ever done, and they've done many. It sounds amazing in surround sound and even stereo, and gives you more insight to the writing brilliance of Jagger and Richards. Best example; Gimme Shelter. The best intro of their catalog and almost any rock song with its haunting guitar and vocalist while being a 3 chord song.
Another factoid for Stones fans: Sympathy For the Devil has no drums in it. The percussion is from bongos, maracas, and a caribbean guiro with stick that gives a high-hat sound and more melodic that maracas. Also, probably the most under-rated bassist in RnR is Bill Wyman. He not only did his base runs, but filled in the rhythm section that was missing Watts' drums.
I had fun in the 60’s especially in high school (Class of ‘66). In ‘65, my friend and I saw the Stones live at the San Francisco Civic Auditorium. We were so stoked that we started a band, playing mostly Stones because they were usually easy to play, at parties.
BTW, an opening act for the Stones then was Paul Revere and the Raiders - they were a great show. Mark Lindsay of the Raiders was almost as good of a live act as Mick Jagger of the Stones. A lot of fun.
