I was watching a programme on accents recorded by German researchers from POWs in WW1, and one of the common pieces was the parable of the prodigal son, beginning, "There was a man who had two sons..." when out from my dim and distant memory swam a song. I do not know its origin or where I learned it(certainly not from a US university song book, which provides the nearest match).

Any ideas?

There was a farmer had two sons, and these two sons were brothers,
Josephus was the name of one, Biancus was the other.

Now these two brothers had a pig, and it was double jointed,
They took it to the blacksmith's shop, to get its trotters pointed.

Now these two (men) fell sick and died, from eating apple jelly,
Josephus died upon his back, Biancus on his birthday.

Line missing, ending with "ell"
Josephus he went up to heaven, Biancus went as well.
