Who Are You? (Black Sabath)

Yes I know the secret That's within your mind You think all the people Who worship you are blind You're just like Big Brother Giving us your trust And when you have played enough You'll just cast our souls Into the dust Into the dust You thought that it would be easy From the very start Now I've found you out I don't think you're so smart I only have one more question Before my time is through Please I beg you tell me In the name of hell Who are you? Who are you?
