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?
[ Lyrics from: http://www.lyricsmode.com/lyrics/r/radiohead/wish_you_were_here.html ]
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...
