Talk:Boris Karloff "Monster Mash" Rendition (Lost 1965 "Shindig!" Footage)/@comment-9469140-20141022222618/@comment-24087447-20141022223220

I am guessing he kinda flubbed his performance so the TV execs hid away the footage to prevent further embarassment.

Or they were afraid that this version would overshadow the original Monster Mash since it is the real Boris Karloff and not an impersonator, thus preventing more sales.
