Mrrzy, I just heard a song performed on the Conan O'Brien TV show, by one A.A. Bondy, thatI think would be ideal! Fortunately he (A.A., that is) has a YouTube video of himself playing this song on guitar with some simple chords, so you can probably learn the song quickly:

A.A. Bondy, "American Hearts" on YouTube

Lyrics to "American Hearts" (not 100% sure these are correct -- the source says he transcribed them by ear -- in fact I corrected some of it below to reflect what I heard on Conan):

We were raised by wolves
And we are still wild
And we howl when a troubled wind blows
And in the TV's blue light
Oh, assassins will lie
Every wail just a-goin' down slow

Now don't tread on me
For I am your brother (and)
I was born with an American heart
And don't tread on her
For she is your sister (and)
She was born with an American heart

All the people you meet
Down in the street
May be good but they don't wanna know
So they cover their eyes
For who wants to be sad?
Life is sweet at the bottom of the sea

Now don't tread on me
For I am your brother (and)
I was born with an American heart
And don't tread on her
For she is your sister (and)
She was born with an American heart

And the mothers will cry,
Fathers stay up all night
With a worry that goes to the bones
And if your God makes war
Then he's no God I know
There's no Christ that would send boys to die

Now don't tread on me
For I am your brother (and)
I was born with an American heart
And don't tread on her
For she is your sister (and)
She was born with an American heart

(And) Don't you get low as hell
When the peace dove is felled
Them men always got the blackest of minds
   (or, "Those men got the blackest of minds" -- see link below)
And above the din
Let the sighin' begin
As we're bound for the longest of days

And don't tread on me
For I am your brother (and)
I was born with an American heart
And don't tread on her
For she is your sister (and)
She was born with an American heart

(Slightly different lyrics are in this YouTube performance by A.A.: Bondy with band, "American Hearts")
