The vengeful christ song about the beasts ploughing is Roud S156927.

The original recorded by Fred Hamer from May Bradley, found in the book Garner's Gay and on the CD "Century Of Song" EFDSS 1998.

It has also been recorded by Spiers and Boden.

Both recordings use the title "On Christmas Day."

At the risk of a far too blatant plug - the May Bradley version will be broadcast towards the end of my programme Thank Goodness It's Folk tomorrow, along with a number of other carols. It's in the second half (first half is an interview with Martin Simpson (!!) )

I also did a whole hour the week before this is still available via the web.
