Notes

Black pudding is a blood sausage associated with northwest England, where Granny & Pop lived for most of their lives.

Oct 2023:
Following a spike of interest in this entry I dug a bit and discovered that it’s from a song reasonably well known in northeast England.

The relevant verse, in one version, runs thus:
All of a sudden a little black pudding
Came flying through the air
It missed my Ma, and hit my Pa
And knocked him off his chair
…which just happens to be the least rude part of the song in every variation I found.

The general consensus on mudcat.org seems to be that it should be sung to the tune Blaze Away (by Holzmann but sounds as if it should be by Souza).
