In 1967, Bruce Lee appeared at the tournament as "Kato" and demonstrated his one-inch punch and two-finger push-ups. His volunteer was Bob Baker of Stockton, California. "I told Bruce not to do this type of demonstration again", he recalled. "When he punched me that last time, I had to stay home from work because the pain in my chest was unbearable." The only existing, high quality footage of Bruce Lee's 1964 Wing Chun demonstration was filmed with a 16mm camera. The sole proprietor of this 8.5-minute-long video is a California-based company, Rising Sun Productions. The owner of this company and reported discoverer of this video is Don Warrener. Poorer quality generations of this footage can be viewed on the Internet.
