Looks like an imitation of a gang work song of the late 19th c.

I can't find a thread for these songs that are used when work gangs have a task that requires a rhythm and meter for work in unison. Few appear in collections, perhaps because they are repetitive and lack the interest of ballads. Many were made up at the spur of the moment, and words would vary from day to day.

I will start one later today.
