Mark, you posted the same video twice.
To be honest, I think what ever he's doing in the video looks horrible. I'm not a forms person but I can appreciate something that flows and has strength and is artistic but this, this looks like a monkey humping a football; awkward. I see there is a second video of this guy called " Early Kuntao Silat DeThouars - Uncle Bill Part 2"
where he is at a farm, it looks more like he is doing a chicken dance.
