Lennon wrote one about “Revolution”.
He clearly wanted nothing of those revolutionaries advocating violence.
Put away the crack Bill.
In the first (slow) version of 'Revolution' Lennon sang 'But when you talk about destruction ... don't you know that you can count me out ... in"
In interviews he said that initially he wasn't sure if he was for violence or not. When they recorded the higher tempo / electric guitar version, he just said 'count me out' because he had decided violence wasn't the way.
But he was on the fence about it for a while, at least.
And if you're carrying pictures of Chairman Mao...
You ain't going to make it with anyone anyhow...
But if you want money for people with minds that hate
All I can tell is brother you have to wait
Some celebs should pay attention to that second couplet.
