My word, edgar, that song has been sung in many different versions and from different cultures. My mom sang it to us when we were kids. That one, of course, is updated.
This was a surprise, y'all. Although it doesn't play through until the end, I think that I can provide the final chorus.

Here is the wedding party as I remember it.
The first to come in was the old gray goose, unhuh
The firest to come in was the old gray goose,
Every tooth in her head was loose, unhuh.
The next to come in was the little black bug, unhuh
The next to come in was the little black bug,
He had whiskey in his jug, unhuh
They all got eaten by a big black snake, unhuh
They all got eaten by a big black snake,
He soon died with the tummy ache unhuh.
There is also a Scottish version to that song.
