Listen   if you listen   you will hear an endless heartbeat   on the inside   through the walls   the sound is crawling   down the corridors and halls   it cracks the ceiling   the windows and the doors   all the rest won't listen   though the walls have ears   but they never really look   they just stand and stare   they're all standing   staring at the walls      who put the writing on the walls?   will no-one ever know?   Oh, well I don't mind the walls      Tell me   why don't you tell me?   have you got nothing to say?   tell me where in hell this place is   tell me why I get no answers   am I talking, taking to the walls?   so it's running, jumping, standing still   well I think I've had enough of it all   get your hands up   up against the wall   (well, I'm never going back to the factory   no I'll never be a part of the machinery)      who put the writing on the wall?   who fights and runs away?   the minutes and the hours pass him   tracing out the days   the days and nights drag into years   and no-one ever knows   Oh, well I don't mind the walls   Oh, well I don't mind the walls   I don't mind the walls
