You say you want a revolution.
Well you know, we all want to change the world.
You tell me that it's evolution.
(...)

You say you got a real solution.
Well you know, we'd all love to see the plan.
You ask me for a contribution, well you know, we're doing what we can, but if you want money for people with minds that hate, all I can tell you is "brother you have to wait".
Don't you know it's gonna be alright? Alright alright!

You say you'll change the constitution!
Well you know, we all want to change your head.
You tell me it's the institution.
Well you know, you better free your mind instead, 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?

Revolution, por Beatles.
