About the Song

[Hades]
Why do we build the wall, my children, my children?
Why do we build the wall?

[All together]
Why do we build the wall?
We build the wall to keep us free
That's why we build the wall
We build the wall to keep us free[Hades]
How does the wall keep us free, my children, my children?
How does the wall keep us free?

[All together]
How does the wall keep us free?
The wall keeps out the enemy
And we build the wall to keep us free
That's why we build the wall
We build the wall to keep us free[Hades]
Who do we call the enemy, my children, my children?
Who do we call the enemy?

[All together]
Who do we call the enemy?
The enemy is poverty
And the wall keeps out the enemy
And we build the wall to keep us free
That’s why we build the wall
We build the wall to keep us free[Hades]
Because we have & they have not, my children, my children
Because they want what we have got[All together]
Because we have & they have not
Because they want what we have got
The enemy is poverty
And the wall keeps out the enemy
And we build the wall to keep us free
That’s why we build the wall
We build the wall to keep us free[Hades]
What do we have that they should want, my children, my children?
What do we have that they should want?

[All together]
What do we have that they should want?
We have a wall to work upon
We have work & they have none
And work is never done 
My children, my children
And the war is never won
The enemy is poverty
And the wall keeps out the enemy
And we build the wall to keep us free
That’s why we build the wall
We build the wall to keep us free
We build the wall to keep us free
