North Devon Aikido Club at Holsworthy and Bucks Cross, between Bideford and Hartland
Excellent video of a great master demonstrating the partnership of Jo with self. There are lots of small points where it is possible to see similarities in the 31 as taught by Saito Sensei. Huw kindly pointed out several moves at the beginning but I've now found a few more later on . . . not exact but it is possible to see sufficient likeness to indicate the one source.
