I forgot to add that Bruce quoted a verse in an old discussion here:

There dwelt a stranger in the court,
Sinior Dauid calde by name,
He was the first that went about,
This treason vile to frame.

This may, of course, not be in the recording I mentioned earlier.

I may have done Susan an injustice: from the little that can be made out in the online sound sample, the words 'woe worth, woe worth' certainly do appear, as they also do in 'Earl Bothwell'. The rest (so far as I can tell from the poor sound quality; probably sung a bit too fast for clear articulation) is, however, completely different.
