That’s Lindsay Lou singing. Vocals, guitar, double bass... check her out with the Flatbellys. She’s really good. Done some nice Joni Mitchell stuff with Molly Tuttle.
"Mighty fine," to borrow Lester Flats words of praise. No offense to Stanley Brothers or Jimmy Martin but this is my favorite rendition of this timeless classic.
Joyce Thomas yes he is, it's his mahogany Thompson one of two he owns. This one is not seen much since he acquired his Martin. His other Thompson is a rosewood sunburst.
