Here's the link to the fight that took place in Macau in 1954 http://kwoon2.free.fr/NgvsChan.WMV
The old fighter is Ng(Wu) Gong Yee(Wu TC). He is the son of Ng(Wu) Gan Chuan. The guy doing a form demo in the beginning is Dong Ying Jei, a student of the famous Yang Ching Fu(Yang style large frame).
The White Crane style here is Tibetian White Crane, master Chen (the younger fighter) has boxing background also. Some one says that Chen might still be alive
