This is not -stricto sensu- a slide but the lovely kinda~12/8 lilting melody of the eponymous song.
A version appears on the 1976 Bothy Band album collected from Nellí Ní Dhomhnaill ‘in May of [that] year’.
So the notes tell us as well as that it ‘has probable connections with Child 299: The Trooper and the maid’.
"As I went down yon heathery moor,
I met a bonnie wee lassie
She winked at me and passed me by…"
It isn’t the sometime eponymous:

A dorian? there’s a hing of G major in it and the only C in the melody could equally be sharp.
My original ABC had a pause on each doted crochet (d, G…)
To turn this song tune into a regular 12/8 slide will take more than cutting back those long notes. Post your endeavours here if you fancy.
