Here is what there is of the 1977 Mr. Olympia.
If you start around 9:50 and can watch to the end
you get a good commentary from Arnold S. himself.
The video is pretty weak up to the 9:50 mark.
People back then went bat shit crazy at BB contests.
Arnold has to speak very loud to come in clear over the audience.
Zane was in better shape than anyone but Robbie R.
is really the only one who has that WOW factor. He was
just too smooth for this one. He would win a lot of contests
during the year in great shape and never brought his best
to the Olympia.
In this shape here at the Night of Champions he would have beat
Frank.
