Long John
The tune that Leonard Rutherford & Byrd Moore attempted on 29 October 1929 (14395- Gennett rejected) was "Lost John." Leonard Rutherford & Richard D Burnett recorded "Lost John" as a fiddle/banjo duet on 6 November 1926 (143092-2) released as Columbia 15122-D. W. L. Gregory & Clyde Davenport recorded "Lost John" which Mr. Gregory learned from Leonard Rutherford. That tune sounds pretty different from Bob Walters' "Long John" to my ear.
