Consider yourself lucky. I think the extra bits really drag the whole pace of the scene down (which is, I'm sure, why it was cut in the first place, and why I'm bothering re-cutting it).
The original 2000 DVD release may very well not have the extra Anthrax scene, yes. But I'm doing all of this based on the Blu Ray release, editing to match those frames (more or less).
So, having looked at the sequence now, I could probably still use some reference frames (I can probably work with the CED frames but I'm not sure how accurate they are). It looks like the cuts are not made during a camera change, so with the scene removed it may "jump" a bit at the cut point. A frame on each side of the jump is what I'd like ideally.
