We recently discovered (through Newspapers.com) that the announcement was published on page 8 of the August 31, 1975 issue of The Corbin Times-Tribune. The concert was part of a larger newspaper advertisement and promotion of a Labor Day sale at the Howard Brothers Discount Store in Corbin, Kentucky. Timi was almost 12 years old at the time, and while she doesn't remember this concert in particular, she said she was likely there with her grandparents selling 45's in the parking lot. She remembers the Howard Brothers store, which was part of a larger chain of departments stores in the Southeastern US.
Frances and John recorded on the Cincinnati label in 1973 as John Reedy and The Stone Mt. Trio, which was a 45 of "Little Sparrow" and Frances' song "Tiny Bitty Pieces" (Jewel 1017). So they may have encountered the Bluegrass Drifters through their connection to the Jewel label, but they also could have crossed paths with the band at Renfro Valley. In his book It All Happened in Renfro Valley (1999), Pete Stamper recounts that in the late 1960s "... the Bluegrass Drifters, Renfro Valley's second Bluegrass band, was expanding its role on the show. They would establish themselves as a permanent fixture in one way or the other for a long time to come. The group included lead singer/guitar player John Cosby; Bill Ferguson, playing bass; Charles Durham, playing fiddle; and Vester Parker on banjo" (p. 111).
Whether the Reedys and the Bluegrass Drifters met in Cincinnati or Renfro Valley, this piece of history shows that something was happening in Corbin as well.
