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 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 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 you found? The same old fears.
Wish you were here.
