So you think you can tell
Heaven from Hell
Blue skys 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 heros for ghosts
Hot ashes for trees
Hot air for a cool breeze
Cold comfort for change
Or did you exchange
A walk on part in a war
For a lead roll 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.
– Pink Floyd: David Gilmour, Roger Waters, Richard Wright
