This video was included in the extra features of Ip Man’s release overseas. I have absolutely no idea why both music and movies sometimes differ from Europe and the US, but apparently this was exclusive to the European release.
We recently talked about some of the same positions that Guro discusses as he’s demonstrating trapping and entries/bridging, both in our Inosanto class (working Filipino Boxing entries) and in our Sayoc Atienza class (using entries off the jab to work Karambit techniques).
