Iron Maiden prisoner

I'm on the run, I'll kill to eat,
Starving now, feeling dead on my feet.
Going all the way, I'm nature's beast.
Do what I want, Ido as I please.
Run, you've gotta fight, to breathe, it's tough.
Now you see me, now you don't.
Break the walls, I'm coming out.
I'm not a Prisoner, I'm free man,
And my bloodis my own now.
Don't care where the past was,
I know where I'm going... out.
If you kill me, it's self defence.
If I kill you, then I call it vengeance.
Spit in your eye, I will defy.
You'll be afraid when I call out your name.
Run, you've gotta fight, to breathe, it's tough.
Now you see me, now you don't.
Break the walls, I'm coming out.
I'm not a number, I'm a free man,
I'll live my life how I want to.
You'd better scratch me from your black book,
'Cause I'll run ring around you.
