I like to sing this chorus:

... Do or die, you'll never make me. Because
the world, will never take my heart. ---/ And though you try, you'll never break
me. You want it all, you wanna play this part. I won't explain, or say I'm
sorry. Im not ashamed, I'm gonna show my scar. You're the chair, for all the
broken. Listen here, because it's only.. I'm just a man, I'm not a hero. Just a
boy, who wans to sing this song. Just a man, I'm not a hero...
