The Sound of Silence by Simon and Garfunkel:

 
          Hello darkness, my old friend 
          I've come to talk with you again 
          Because a vision softly creeping 
          Left its seeds while I was sleeping
          And the vision that was planted in my brain
          Still remains
          Within the sound of silence
          I n restless dreams I walked alone
          Narrow streets of cobblestone
          'Neath the halo of a street lamp 
           I turn my collar to the cold and damp 
           When my eyes were stabbed by the flash of a neon light
           That split the night
           And touched the sound of silence 
           And in the naked light I saw
          Ten thousand people maybe more
          People talking without speaking 
          People hearing without listening
          People writing songs that voices never shared 
          No one dared 
          Disturb the sound of silence 
          "Fools," said I, "you do not know
          Silence like a cancer grows 
          Hear my words that I might teach you
          Take my arms that I might reach you" 
          But my words like silent raindrops fell
          And echoed in the wells of silence 
          And the people bowed and prayed 
          To the neon god they made 
          And the sign flashed out its warning
          In the words that it was forming 
          And the sign said "The words of the prophets are written on the subway walls 
          And tenement halls 
          And whispered in the sound of silence
