Eh, personally, I think it was kind of arrogant confidence on Portnoy's part (him being the writer of the set list for every tour from FII through BC&SL), like, "We had it right the first time (the Burning My Soul demo), so we didn't need someone else to tell us what to do." Playing it would be like admitting that someone else knew better than them how to make a song of theirs great.
