Protection (prevention)
Detection (detention)
There's no where to defect to any more

I'm building a wall
fine wall
Not so much to keep you out
More to keep me in

Back then on a bomb site
We were spies among [bad word] Such precocious barbarians
On TV we saw
Cold War

Protection (prevention)
Detection (detention)
There's no where to defect to any more
Protection (prevention)
Detection (detention)
There's no where to defect to any more

I'm leaving the world
It's all wrong.
Not so much what many are doing?
Much more what's within us?

I'm building a wall
fine wall
Not so much to keep you out
More to keep me in

Jesus and the man from Angola
Caesar conquered Gaul
Scouting for Centurions
On a Roman war

Through the woods, the trees
And further on, the sea
We lived in the shadow of the wall
Sand in the sandwiches
Wasps in the tea
It was a free country
(Who do you think you are, Captain Britain?)

I'm building a wall
fine wall
Not so much to keep you out
More to keep me in

I'm losing my head
Well, why not?
More work for the undertaker
Means there's less for me

I'm building a wall
fine wall
Not so much to keep you out
More to keep me in

I'm building a wall
fine wall
Not so much to keep you out
More to keep me in

I'm building a wall
fine wall
Not so much to keep you out
More to keep me in
