This transcription is based on a performance by the Mississippi Mud Steppers, OKEH 45504.
The Mississippi Mud Steppers recording has some unusual harmonies in bars nine and ten that are not reflected in the above transcription. In the recording, the guitar accompaniment plays a chromatic ascending line from C to D, causing bar nine to sound as a Db augmented chord, and bar ten to sound as a E half-diminished seventh chord in third inversion.
