"Stand and fight
live by your heart
always one more try
i'm not afraid to die
stand and fight
say what you feel
born with a heart of steel "

"Tryin to be who you are
the harder you try the closer you'll get
when you fight with a heart of steel
fightin a war you can't win
the only things that stay are you're sins
but you fight with a heart of steel"
