IMO there was no such roller coaster in the 1960s. 70's more like it. You weren't there, so how would you know?I would put a bet on you learning this from some conman trying to take a ride on the cultural kung fu rollercoaster of the sixties!
Others have dealt with your other ignorant,disrespectful and patronising remarks, for which they have my thanks.
I didn't study this style of boxing. However, my first KF instructor, David Crook, was familiar with it and discussed and demonstrated some of its concepts with me while he was teaching me other things. He was also friendly with Erle Montaigue and they corresponded and occasionally joked at each other's expense in articles in the martial arts press at the time.
Erle was a prolific author and probably wrote more and in greater detail on Dim Mak and internal TCMA than anyone else before him. He even spent a bit of time as a pro wrestler in his younger days.
He courted controversy and got into feuds with a number of other prominent Australian and international martial arts identities (some of whom relative newbies like Spencer might not have heard , though they include George Dillman and the Gracies), but undoubtedly the MA scene world wide is better for his involvement and poorer for his passing.
