This song is definitely one of Roger Waters' best lyrical efforts.

C#m 
Could be Jerusalem, or it could be Cairo
B
Could be Berlin, or it could be Prague
A 
Could be Moscow, could be New York
B
Could be Llanelli, and it could be Warrington
C#m
Could be Warsaw
B
and it could be Moose Jaw
A
Could be Rome, Everybody got somewhere they call 
B
home

E
When they overrun the defences
B
A minor invasion put down to expenses
A 
Will you go down to the airport 
C#m (in all the other choruses, this is just a B)
lounge
E
Will you accept your second class status
B
A nation of waitresses and waiters
A
Will you mix their martinis, Will you stand 
B
still for it, Or will you take to the
C#m
hills

And so forth.
