Yes it is Wayne Henderson the ace guitar picker and builder. Carol (Seese) Henderson was his wife at the time. They have a doughter Jayne who follows her father in building instruments. I know too that Carol built a fiddle or two. Wayne's brother Max played in the Grayson Highlands String Band.

Frank Weston did an early interview with Wayne in 1980 which was published in the UK magazine Old Time Music around 1982.

There is an audio track by Uncle Dave on You Tube playing "Breaky Mountain Fog Down" with a still shot. It's on the channel of 'Backup6Box'

The book by Paula H A Green is fine but a more comprehensive book on many many musicians of the area is "Strings of Life" by Kevin Donleavy
