Here's a link to a 10 minute film at Folkstreams.net. I think this one shows Mr.Otha burning out a fice and some picnic shots with the Fife and Drum band doing their thing.
This was filmed at Otha's house outside Senatobia,MS kind of between there and Como. They still hold the annual Labor Day picnic there and now his grand-daughter Sharde, leads the band. Sharde's maybe 14 now.
