I watched the movie A Hard Day's Night recently. It was a basically enjoyable simple thing. Those guys were such droll scamps.
Could not help but notice the complete lack of virtuosity in their musicianship though. As far as writing, there is no denying --> it is right on target. They wanted simple pop hits and they delivered.
But I was kinda like, man, you'd think they'd want to learn how to play those instruments a little better.
