Re "Nobody ask't ye, Sirrah, she said."

We had a variant in our Mother Goose Rhymes book, so I presume it's pretty common. I don't remember the full thang, but it was something like:

Where are you going, my pretty young maid?
(repeated with variations)
I'm going a-milking, Sir, she said.

(Various verses, all ending with "..., Sir, she said."

Last verse, he concludes that he won't marry her;
"Nobody asked you, Sir," she said.

So, I presume this was a stripped-down, no-burden-or-chorus version of the song you're talking about.
