Happily, yesterday fell on a Sunday so I was able to sing "A Week Before Easter" (as learned from Dransfield) on its proper day.  Even though it's in Greig, I think of it as the English version.   I've known what I think of as the Scottish version,  "I Ainse Loved a Lass" (MacColl, Cameron, etc.) many years as well.

There's a good bit of discussion (& so should be) on this song, "The False Bride."

In my limited mind, however, I can't hold the two tunes side by side long enough to reckon if there are enough similarities to call them the same tune.

It's a good song regardless & one of those worth singing, it seems, in any of its versions.  Just curious.
