Pink Floyd. Wish you were here.

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.
