Sundome1 has placed many good clips on youtube but IMHO this is his best -a great collection and very nostalgic for many of us. I had trained with many of the Instructors featured at one time or another - some passed now.
I won't spoil it for you but watch for the old B&W clip of Enoeda Sensei at 19yrs old. those who new him will see that same grimace of absolute determination on his face, when faced with an opponent, that he had till he passed.
Also look at Tanaka Sensei's total calm when competing in the JKA - so much so that he tricks his opponent in a very funny way before banging a mae geri into him. it comes at about 8.16
enjoy folks - see haw many you can name without looking it up.
and if sundome1 ever reads this - respect sir, respect. and you are right this is our heritage our source - excellent
