Could be a nice touch. Examples follow:
Stand up and be counted
No more time for doubt,
stand up
Stand up!

Reaching out - so cold!
What did I say - did I do
To lose my hold on you?
Reaching out with
all that I could give
What should I say - should I do
To make you....
...sign back in?

This one falls short of brilliant, since we're not the Cage, but the Shattered Room:
Welcome, welcome, welcome to the cage
Welcome, welcome to the world we made

This is good, if a bit dramatic:
The fellowship started here
With righteousness and lunacy
The covenant started here
With screaming souls and vitriol

How 'bout this to the ones who left:
Fly to the valleys, fly to the hills
Try to exist on your own without feelings
Ripping your soul beyond all recognition
Unforgiven, twisted vision
Let your conscience decide!
Can you live with yourself
and the deed you have done
Conquer your thoughts when all this has begun
It's tearing your mind into guilt and regret
Troubled dreams - You'll not forget this!
