P.S. My primary videocamera stopped recording, though it kept video-streaming to Bill Bosari's set-up. I switched over to the back-up camera, but then that starting having problems, so I went to the back-up, back-up camera. When the battery on that
third camera juiced itself out, I went back to the first back-up which completed the filming. Whew!
P.P.S. In a 5-hour editing session, I stitched together the videos of the 2 different back-up cameras. The sound is complete, though the video has two short gaps. I've replaced the missing footage with still clips of Mike! :)
