Today's concert-goers do not seem to realize that, before Brian's Boys, nobody used to scream and carry on like they do now. Even when Elvis performed it was not nearly that bad. A lot of parents were truly worried ~ this outlandish behavior just seemed wrong!
The above vid might make it a little clearer how very much things changed due to Beatlemania. XD
It was either Debbie Geller or Ray Coleman speaking with Queenie when she recalled how Brian kept asking her to describe the same kind of behavior, the hysteria that went on around Rudolph Valentino in the 1920's.
No doubt the Valentino Effect came to mind the first time Bri visited the Cavern with Alistair Taylor! :D
Example of Valentino onscreen ~
Rudolph Valentino died the same week (41 years earlier) as Brian.
Brian Epstein ~ August 27, 1967, age 32.
