I have checked digitrad for the lyrics, but I remember long ago a version in which the performer (Leadbelly?) spoke ... something like the station master asked what he had and he answers something like 'I got cows ... I got sheep ... I got all live stock ' and the station master lets him go and he says 'I fooled ya .. I fooled ya .. I got all pig iron, I got all pig iron.' and then it works into the singing part.

Can anyone help me with the actual lyrics for this?

many thanks ... Edmund
