Here is the version from Brooklyn, New York in the early 70's...the Brownsville version:

Ahh, Beep Beep!
Walking down the street
Ten times a week
Ungawa!
Black Power!
Destroy!
White Boy!
I said it, I meant it
I'm here to represent it
I'm cool, I'm calm
I'm Soul Sister Number Nine
Sock it to me one more time!
Uh-Uh! Good God!

Now someone here mixed this up with another soul sister/brother rhyme that goes as follows:

I'm a bad soul sister from a bad soul town
It takes 48 whites just to knock me down
Don't you pick no apples from my apple tree!
I'm a bad soul sister, don't you mess with me!

We had so many rhymes like this. Some were very graphic!
