On her album "Òg-Mhadainn Shamhraidh", Kathleen MacInnes does sing the same lyrics as I got from the Mànran website and posted at the beginning of this discussion.

I think the transcription from the BBC is the complete song. Kathleen MacInnes sings some of the verses; Mànran sing some of the verses, Mairi MacInnes made a slightly different selection. And perhaps Kathleen MacInnes doesn't even always sing exactly the same verses ...

I haven't tried to compare all the recordings of Kathleen singing Òran na Cloiche which are posted on youtube, but I did listen to the album recording https://www.youtube.com/watch?v=gWe8eotofRA&list=PLp2_g9qArV7t6xRSEtZEP4Vxwyt1aKp_S while looking at the written lyrics and it matched the Manrán version.

I prefer another recording where she sings more slowly: https://www.youtube.com/watch?v=6KUK5gR1jcY - but it doesn't include the verse which concludes that the man who took the stone must have been as strong as a horse, "Bha’ n duine thug à sàs i cho làidir ri each”

Celtics Lyrics Corner also has lyrics for a recording of Òran na Cluiche by Màiri MacInnes.
