Born on the 4th of July

Raised in the barnyards of heroes and cons
Left me for dead or alive
C		    F    G    C
There is a war that's inside my head
That questions the results and lies
         C		                 F    G      C
I'm breaking my back till I'm better off dead
We are not payed enough to survive
C	               F      G    G
I am an engine, a worker, a pawn
My debt to the status quo
C			   F    G      C
The scars on my hands and a means to an end
It's all that I have to show
C		     F   G  C
I'm taking a loan on my sa  ni  ty
For the redemption of my soul
C		          F   G   C
WelI am exempt from this tra  ge  dy
And the 21st century fall

I praise liber  ty, the freedom to o  bey
