You say you want a revolution, 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.

You tell me it's the institution, well, you know, you better free you mind instead. 

You ask me for a contribution, well, you know, we're doing what we can. 

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