Canadian Strong Man (Jon-Mikl) Thor
The Wild Bull of the Pampas, Pampero Firpo
It's likely these two could've had a match even though, if memory serves correct Thor never stepped into the ring and wrestled. Yet hypothetically speaking, the AWA ran matches in Winnipeg and Thor and his band likely played some early gigs there in the early 70's when the Firpo promo was shot. *Sigh* I'll just leave it as a True Rock n' Wrestling connection "What if...?"
