Thanks for the 'new' verse Gutcher! I'm very interested in Diva's too, if it/they are to hand.

I recently acquired a photocopy of Ramsay's text, the oldest known (1724 I think), which has no place names or personal titles, however an older version of the tune is in the Skene mandora ms (c.1620 acc to wikipedia) where it is called Lady Cassilis' Lilt. If the date is correct that does put it before the 6th Earl.

There's a lot more to be said on this one I think but I imagine Sigrid Rieuwerts has covered it?
