Lyrics of Keeper of the keys

Could we possibly see
The keeper of all the keys
One key to rule them, he keeps in the great hall
??? tower we call
Now we beat on the drum
But wary a damsel's call
And now the children the oracle has seen
Playeth the old debts of his creed
And he doesn't even realise
He doesn't realised
That it's all happening
Let him know there's a change
Coming up behind him
While he's hanging on to the chain
That's the key that binds him

Now the changes are made
??
Six feet the wind blow and eyes above do breeze
Song for thee oh, keeper of the keys
And he doesn't even realise
He doesn't realised
That it's all happening
Let him know there's a change
Coming up behind him
While he's hanging on to the chain
That's the key that binds him

The keeper of the keys
The keeper of the keys
The keeper of the keys

It's all over now
It's all over now
It's all over now
