Concentration moon
Over the camp in the valley
Concentration moon
Wis I was back in the alley
With all of my friends,
Still running free:
Hair growing out
Every hole in me
American way
How did it start?
Thousands of creeps
Killed in the park
American way
Try and explain
Scab of a nation
Driven insane
Don't cry
Gotta go bye bye
Suddenly: die die
Cop kill a creep!
Pow pow pow

Concentration moon
Over the camp in the valley
Concentration moon
Wish I was back in the alley
With all of my friends,
Still running free:
Hair growing out
Every hole in me
American way
Threatened by us
Drag a few creeps
Away in a bus
American way
Prisoner: lock
Smash every creep
In the face with a rock

Don't cry
Gotta go bye bye
Suddenly: die die
Cop kill a creep!
Pow pow pow
