The Wall Song

You are walking You've always been walking Stumbling half-blinded and dry as the wind That strafes you and leaves you to lie in the sand And the wall stretches endless beside you to nowhere This wall that you've been trying to cross for years This fence made of fears No one hears You see a door Ah, such a great open door You know that's your eyes telling lies, still you chance A shambling run, a ridiculous dance Like a scarecrow that's hung up to dry on a fencepole And there's a space like vacuum waiting inside you For you to get through, yes To the blue You scent the water Fresh, clean grass, food and water Your breath is scraping your brain into dust Your rusty old engine is ready to bust You cannot believe it that they would not trust you The door is wavering, is that your eyes? Are they still telling lies? What are lies?
