When I was in the Army, one of my favorite marching cadences was “The Army Colors”.  This is slightly different.

The zombie colors
The colors are red
To show the world
That we’re undead

The zombie colors
The colors are black
To show the world
We’ll eat your back

The zombie colors
The colors are blue
To show the world
We shamble on through

The zombie colors
The colors are white
To show the world
We own the night
