Kentucky Mountain Barn Dance
Live Saturday night shows, often broadcast on radio WVLK  from 1949 to 1951
Usually at Clay Gentry Arena but occasionally at Woodland Auditorium

Often attended by a young J.D. Crowe, especially when Flatt & Scruggs were featured! Crowe can be seen sitting in the aisle on the sixth page of the SONGBOOK, and dates when Flatt & Scruggs were advertised can be seen in the newspaper ADS.
