Ron found this the other day and at the time of this post is the number one video on Youtube featuring Shihan Sig Kufferath, who was the head of Danzan Ryu Jujitsu at the time. Video is from circa 1987 at my old dojo in Los Angeles.
When Ron showed me the video I didn't realise at first that it was Sig and me from back in the day - could hardly recognise myself!
The other person in the video is Professor Michael Belzer, my Sensei in the US and an 8th dan in Danzan Ryu Jujitsu as well as instructor of Japanese Jojutsu and his own system known as 'Sabaku Jutsu' or Cement Jujutsu.
Professor Sig Kufferath was quite a character and also an amazing martial artist; he was in his late eighties when this video was shot.
