Wish you were here.. Pink floyd

So, so you think you can tell ..Heaven from Hell,blue skies from pain...Can you tell a green field..from a cold steel rail?A smile from a veil?Do you think you can tell?And did they get you trade...your heroes for ghosts?Hot ashes for trees?Hot air for a cool breeze?Cold comfort for change?And did you exchange ..a walk on part in the war..for a lead role in a cage?..How I wish, how I wish you were here.We're just two lost souls swimming in a fish bowl,year after year,running over the same old ground..What have we found?The same old fears,wish you were here.
