America was not alone; banning the Beatles was a very popular thing to do. At least one radio station in South Africa, Spain, Holland, and Israel, to name a few, joined in at different times and because of different songs. The BBC even got into the act, banning songs for supposedly promoting drug culture and including the name of a brand. Israel also banned the fab four from playing there until 2008 - the "unbanning" and apology coming a bit late in the day!
The ban in the U.S. resulted , mostly, from John Lennon's statement to the London Evening Standard, on Mar 4/66.
Christianity will go. It will vanish and shrink. I needn't argue with that; I'm right and I will be proved right.
