So, so you think you can tell Heaven from Hell,
blue   from   .
Can you tell a   field from a cold   rail?
A   from a   ?
Do you think you can tell?

Did they get you to   your heroes for ghosts?
Hot   for trees?
Hot air for a cool   ?
Cold   for change?
Did you   a walk on   in the war
for a lead   in a   ?

We're just two lost souls swimming in a fish   ,
year after year,
Running   the same old   .
What have we   ?
The same old fears.
Wish you were here.
