Building a wall

Protection! Prevention! Detection! Detention!
There's nowhere to defect to any more!
Protection! Prevention! Detection! Detention!
There's nowhere to defect to any more!

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

Back then on a bomb site we were spies among the ruins
Such precocious barbarians, on TV we saw cold war

Protection! Prevention! Detection! Detention!
There's nowhere to defect to any more!
Protection! Prevention! Detection! Detention!
There's nowhere to defect to any more!

I'm leaving the world, it's all wrong
Not so much what men are doing
Much more what they're not
I'm building a wall, a fine wall
Not so much to keep you out
More to keep me in

Jesus and The Man From Uncle
Caesar conquered Gaul
Scouting for centurions on a Roman wall
Through the woods, the trees
and further on, the sea
We lived in the shadow of the war
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, a fine wall
Not so much to keep you out
More to keep me in
I'm losing my head - well, why not?
More wood for the undertaker
means there's less for me

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