This piece is an abbreviated version of Furry Lewis' East St. Louis Blues, only as much as I can recall hearing John Hammond perform it on his 1963 eponymous album. Vocals, Guild acoustic and "kitchen percussion" by Kathleen Martin [kat330] Piano by Damien Riba, Courtesy of Mangalyan Records.

This is one of the on-hold music selections at credivoice.com which is where I first heard it and was trying to find it.
