This column by Jim Proudfoot appeared in the Toronto Star on August 1, 1970. It's a nice story about the success Angelo Mosca was having as a pro wrestler -- particularly his work for Roy Shire in Northern California as Hercules.
The only problem with the piece is that I can't find any record of a wrestler named Hercules working for Shire at the time.
The late Ron Valim kept detailed records of Shire's shows in San Francisco and other cities in the territory, and there's no Hercules to be found.
So was he using a different ring name with Hercules as a nickname? I don't see any likely candidates in Valim's results. Other than a few prelim guys, the workers Shire was using at the time are all well-known wrestlers. I don't see anyone who could have been Mosca.
In Proudfoot's column, Mosca is quoted saying the shows could draw 30,000 people to the Cow Palace in San Francisco. That's about double the actual maximum (the annual battle royal in November 1969 drew 15,974 and that seems to be the biggest crowd of the year).
Was the whole thing made up?
