wish you were here lyrics

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?

Did they get you to 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 a 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
