Don't be surprised, lol. Most licensed materials (especially the "warhorse" shows owned or once-owned by Tams-Witmark, etc) are hardly ever updated - except in the case of a wholly brand new version. (And in this case, there is the new David Lee rewrite - but the original materials remain what they have always been.)
But yes, I'm sure there is never an issue in making that cut.
I haven't done an older Tams show in a while, but I wonder if they still send out the "sides" books as an option? Those things are abhorrent.
(FYI, Camelot is now owned by MTI - but the materials haven't changed.)
