And if there is no room upon the hill and if your head explodes with dark forbodings too I'll see you on the dark side of the moon The lunatic is in my head The lunatic is in my head You raise the blade, you make the change You re-arrange me 'till I'm sane You lock the door And throw away the key There's someone in my head but it's not me. And if the cloud bursts, thunder in your ear You shout and no one seems to hear And if the band you're in starts playing different tunes I'll see you on the dark side of the moon
