By the way, I just checked youTube and there are several of my NFB films which are not currently on the NFB site. Usually the NFB lawyers are hard at work getting them taken off, but they seem to be napping. Rather than give individual links, (since they come and go), you can just go to youTube and type john weldon or john f weldon into the search box. Lately I found:
To Be
The Lump
Spinnolio
and Para Sight.

Yes, there are other john weldons, mainly a theologian, but i don't think anyone's gonna mistake him for me!
