Lyrics
Context: Oh you tell me that there's danger to the land you call your own
And you watch them build the war machine right beside your home
And you tell me that you're ready to go marchin' to the war
I know you're set for fighting, but what are you fighting for?

“Try fighting with your head for a change…
it's a good one, even if it does resist learning.”
