It's a pity the two (very short) clips start in the middle of a verse, making it difficult to immediately recognise the tune. Neither of them are the same as the three I've mentioned and sound a little like that usually associated with 'The Night Visiting Song' (I must away, love, I can no longer tarry........). As both Ossian and Capercaille are Scots groups, perhaps they've come to it from a different source.
