Protection, prevention, detection, detention
There's nowhere to defect to anymore
Protection, prevention, detection, detention
There's nowhere to defect to anymore

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 anymore
Protection, prevention, detection, detention
There's nowhere to defect to anymore

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 U.N.C.L.E.
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

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