Revolution

This song is stuck in my head today. Can't imagine why:

You say you want a revolution
Well, you know
We all want to change the world

You tell me that it's evolution
Well, you know
We all want to change the world ...

You say you got a real solution
Well, you know
We'd all love to see the plan...

But if you go carrying pictures of chairman Mao
You ain't going to make it with anyone anyhow...

Don't you know know it's gonna be alright
Alright, alright...
