It's debatable whether Baile Leo (An Bhean Úd Thall, A' Bhean Eudach, Thig am Báta, etc) is actually a version of Child 10. There are significant differences.

In answer to an inquiry Tom Munnelly told me that Twa Sisters, Child 10, had not been collected in Ireland. The version recorded by Clannad was originally collected in America and they got it from Derryman Brian Mullen, I understand.

There may be recordings available of The Cherry Tree Carol as it was in the repetoires of Brigid Tunney and Thomas Moran. I'd like to hear and/or read their versions and I'd especially like to have the reported verses in Irish and Scottish Gaelic.
