I was a kid & remember watching w/ my parents who I recall not being too impressed so therefore I wasn’t . When Rubber Soul & Revolver came out, it all changed!! Ground breaking stuff from supremely talented artists & the world never looked back. They could & did it all in their own style: harder rock, folksy love songs, spiritual / deeper meaning songs & just fun stuff.
I told my Dad about 30 years ago that the Beatles would one day be considered to have as much worldly influence & be more famous than Beethoven or Mozart & he said no way. Not long before he passed away a couple years ago, he agreed. Truly great artists & art endures. People will know & listen to the Beatles for a long time.
