The Songs of Charlie Monroe & the Kentucky Pardners: Vintage Radio Recordings from 1944 (County Records County 539, 1974) draws from transcription discs Charlie Monroe preserved from the 1944 WBIG Noonday Jamboree broadcasts in Greensboro, North Carolina, released thirty years after the performances. Monroe plays guitar and sings lead; Gladys "Bobbie Jean" Flatt plays guitar and sings; Tex Isley plays electric guitar; Lester Flatt — in a pre-Blue Grass Boys role — plays mandolin and sings tenor on select tracks; Helen "Katy Hill" Osborne plays banjo; Paul Prince plays fiddle; and Birch Monroe plays fiddle and sings bass. The recordings document Charlie Monroe's working band in a pre-bluegrass old-time country format and preserve a documented early performance by Lester Flatt before his 1944 departure to join Bill Monroe's Blue Grass Boys — one of the most historically significant sideman appearances in the American string-band tradition.
