The entire article is an excerpt from “Famous Father Girl,” by Jamie Bernstein, Copyright © 2018, the daughter of Leonard Bernstein.
It's about when their Dad took Jamie and her brother, Alexander, backstage to meet the Beatles.
She also writes of when Bernstein started "regularly incorporating the Beatles, and other pop music, in his Young People’s Concerts, to illustrate his various points. It kept the kids in the audience interested, just as it had for Alexander and me."
Some remember Beatle-mania. For those who do not Jamie Bernstein does a good job of recounting it through her personal experiences.
This is not necessarily about current Pop Culture, however, it is about a huge plateau in the history of Pop Culture.
