"Jim Harbst's Tune" comes from Jim Harbst who was a traditional fiddler, mandolin and harmonica player, originally from Bradford County and later from Pittsburgh who influenced Mark Tamsula and Richard Withers. He said that he learned this tune when he was young but couldn't remember the name of it. It was recorded by Tamsula and Withers on Behind the Door (2016). The banjo arrangement is by John Letscher from that recording. The recording is in Bb but John worked out the banjo version in D. He says that, like on the recording, this tune goes well with "The Soap Fat Man" in a medley.
