Black Sabbath - Symptom Of The Universe Chords & Tabs

Symptom of the Universe
by Black Sabbath
tabbed by Kramer

I don't understand it, EVERY SINGLE tab i've seen of this is WRONG.  I have a Black Sabbath Video and i can SEE him playing it this way.  Now, he may have it tuned down or what have you, but the notes are still correct.
