The Ultimate Question?

Sitting around during Thanksgiving dinner the discussion got to how things would have been different if my family had moved out of state as we very nearly did, rather than stay in the town I grew up in. Mom noted how that one decision had such tremendous effect because our spouses and kids would all be different.

 

I said that because Paul McCartney had gone to the Woolton Fete as a teenager and met up with John Lennon, the world as we now know it is vastly different than if those two had never met. That got some scorn from some of the older relatives.

 

So the question is - In the grand scheme of things, did the Beatles really change the world drastically, or is that a hopeful myth of devoted Beatle fans?
