I have a lot of respect for the Gracie family – and Hélio Gracie in particular. Here I’ve found this Youtube video, purportedly of Hélio Gracie doing a self-defense demonstration.
What I find interesting about this video is that there are almost no ground-fighting techniques demonstrated – something the Gracies are famous for. The video shows clearly Gracie Jiu-Jitsu’s Judo origins.
Gracie Self Defense
Here are some more videos from the Gracie archive – again notice the Judo (and some of the famous ground technique).
If I had to make a point about these videos it would be to emphasize the difference in training for sport and training for self-defense. This is something I’d like to believe most instructors recognize.
