Isn’t “Revelations” the show at the Dominion Theatre in London? If it is, then it IS included in the Ultimate Collection box set and was released as part of “Totally Bill Hicks” DVD and doesn’t look like it was shot on film.
On a side note, as I have that Ultimate Collection box set, I thought the picture quality on all the DVD’s (Revelations/Relentless/One Night Stand/Sane Man) were very inferior compared to the original DVD’s released throughout the early/mid 2000’s. Content-wise, that box set is tremendous, and the CD’s sound fine but the DVD’s were poor. If you have the original individual DVD’s those shows were released on, hold onto them.
