re: As to wedding poems, when I was a child it was common use at the occacsion of a wedding (or copper,silver, golden wedding feast)that one member of the family laid down the exploids of the couple in an alphabetical epos from A to z on a borrowed melody with a refrain for all to join in.

I have seen these (written out, in caligraphy,) that were given as a post wedding present. (post WWII wedding)

as a kid, i was expected to "sing for my supper" and have a poem or song to perform on holidays.

my other obsession
