To muddy the waters even more and go back to my posting in 2001, I have multiple recordings of this by Donegan. Some have the "Sandburg/Hays" attribution, some just have "Trad", some "Trad/Donegan", some "Trad arr. Donegan" and, in the case of the Belfast Skiffle Sessions, "Trad arr. Donegan/Morrison." so you take your choice!
