David Gilmour Wish you were here live unplugged

So, 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? 
And did they get you to trade 
your heros 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.
