Amos... Stealin' back sounds like one that Jesse Fuller did, although I have to say that I can't be sure that the lyrics were the same. Jesse also did a song called 'The Monkey and the Engineer' which would make good jug band music. Can't remember all of it, but this was the start:-

Once upon a time there was an Engineer,
Drove a locomotive both far and near,
'companied by a monkey who sat on a stool,
Watcing everythin' that the Engineer move.
One day the Engineer wanted a bite to eat,
Left the monkey sittin' on the drivers seat,
Monkey pulled the throttle, locomotive jumped the gun,
And made ninety miles an hour on the main line run!

CH
The big locomotive, right on time,
Big locomotive comin' down the line,
Big locomotive, number Ninety-nine,
Left the Engineer with a worried mind.

THere were about three more verses, I think, Someone out there is bound to know them.
