Got the chance to meet up with Master Tigi Mataalii who was the Tournament Director of the 1966 Karate Championship at the El Camino College, Torrance, CA. He told me that Chuck Norris was doing a demonstration of his Tang Soo Karate. Bruce Lee was a guest of the tournament at that time. He was living in Los Angeles, CA and was shooting The Green Hornet. Master Tigi Mataalii was kind enough to write me a letter of the event.
