While as I stated, there is no known audience shot video, there is "pro-shot" and permission shot video of the show.
VH-1 showed a short 10 second clip on the Rock Show of their 1 professional camera set up at the soundboard with a soundboard audio feed. People associated with Twisted Sister also filmed Anthrax's set, as well as TS, with 3 mini-dv consumer camcorders from various angles.
One of those angles is what you see on the Anthrax BTM.
I would guess that members of Anthrax have this 3 cam mini-dv shoot, but that's only a guess. You can watch a few songs of the TS 3 cam shoot on
www.twistedsister.com .
I myself was at this show, armed with my camcorder. However, being a long time TS fan too, and never having been able to audience shoot TS in the past due to them breaking up in 1987, I only filmed TS. This was the ONLY scheduled TS show at the time, and I didn't want to risk getting seen with my camcorder during Anthrax, and then miss TS.
I know a bunch of you who don't care about TS probably groan at the fact that I purposely didn't film Anthrax but, the fact was that an Anthrax concert at any place and any time was common, but a TS concert was anything but common.
