Now Tom said "Mom, wherever there's a cop beatin' a guy
Wherever a hungry newborn baby cries
Where there's a fight against the blood and hatred in the air
Look for me Mom I'll be there
Where there's somebody fightin' for a place to stand
Or a decent job or a helpin' hand
Wherever somebody's strugglin' to be free
Look in their eyes Mom you'll see me"
Well the highway is alive tonight
But nobody's kiddin' nobody about where it goes
I'm sittin' down here in the campfire light
With the ghost of old Tom Joad
You may also want to listen to the cover released in 2000 by Rage Against The Machine on "Renegades": pretty good, much in RATM-like style.
