I am not terribly pleased that these videos are out there commercially,
as I was the one who had the original SVHS tape that the present copies
are being made from.  I allowed it to be copied purely for informational
use and now they are out there commercially available with sound track
added.  The original films were obviously silent since they were filmed
during the early to late twenties.  The original films are in London in
one of their film museums.
