Don - lucky guess! I wonder if it'd work better if the last verse was in the lord's voice - Tonight you'll lie in a cold open grave, etc.

Here are my own bits of patching (the ones I'm conscious of having done, anyway). My additions in bold:

But the page, he was Lord Barnard's man
And there he would not bide
And he was away to the greenwood
As fast as he could ride

I wanted to emphasise that the page did a triathlon that night (he rode then swam then ran).

The other one is a slightly larger change; it's a bit where I reckon that most versions of the ballad are corrupt, as the normal version of the line doesn't seem to make sense:

Seven long years they were not past
Years had passed but two or three
When she packed up all of her gay gay clothing
She said Lord Bateman she would go see

(If the seven long years had passed she'd have no claim on Bateman any more, so why would she wait so long?)
