Unfortunately, that site won't provide any help that can't be found elsewhere; all the material there is copied from other sites (including the DT), and partially re-formatted without much of the background information, and rarely with sources acknowledged. I am unimpressed by that sort of plagiarism, however good it might appear superficially.
If you're still needing the music, Doug, I have it now, courtesy of my friend Cath James, who kindly copied it for me from Skinner's book. You can get at a midi and a gif of the notation via the South Riding Folk Network site:
The midi doesn't give a terribly good rendition without the expressions, of course; just a rough guide. The staff also includes a variation for the final two bars.
