Could I have eggs, sausage, chips and beans and a tea?

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?

Did they get you to 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 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 fishbowl
Year after year
Running over the same old ground
What have we found?
The same old fears
Wish you were here
