There are 2 different but related songs here. One is the Scarborough Fair type and the other is the Acre of Land type. I always took the latter to be a sort of hand-me-down version of the former. Steve Roud's database surprisingly only lists about a dozen versions of the latter - I say surprisingly because I regard it as a fairly common song. I recorded 2 versions of it in Hampshire on consecutive days in the 70s. Here's one of them, the one that I sing:

My father he bought me an acre of land
Sing over and sing ivy
My father he bought me an acre of land
With a bunch of green holly and ivy

I ploughed up with a ram's horn, etc

I harrowed it with a bramble bush, etc

I sowed it down with some wild oats, etc

I cut it down with my little penknife, etc

I thrashed it out with tail of me shirt, etc

I sacked it up in a mouse's skin, etc

I tied it up with mouses' tails, etc

I sent it to market with a team of fat rats, etc

The thiller* came back with his back broke, etc


*leading horse of a team.

Charlie Hill of Dartmoor also knew a version of which I recorded one verse from him.

Enjoy
