The writer of the A-side, Ralph Raper, had a record shop in Demorest, Georgia, and was also very likely the owner of this label. Another label that he owned was Country Jubilee.
The name of the publisher (Ralph's Radio) appears on various tiny Georgia labels like Lanier (Toccoa), Hillcrest (Cornelia), Self (?) and South Carolina Rush label.
