"Even purportedly "political" Beatles songs are quite naive--e.g., "Revolution":
You tell me it's the institution well you know you better free your mind instead"
Oh, but listen to the limp-wristed tone of that song. It's satiric, no?
"John was a brilliant songwriter, but political strategy was never his forte."
"Working class hero" is a great song. So is "Imagine" -- a great first step.
