"Wish You Were Here" lyrics

So, so you think you can tell
Heaven from Hell? Blue skies from rain?
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 trade your heroes for ghosts?
Hot ashes for trees? Hot air for a cool breeze?
Cold comfort for change? 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 tears
Wish you were here
