I discovered this last night. I think that Bean Dubh an Ghleanna (Dark Woman of the Valley) is quite my favourite melody. I am familiar with it played on the Uillean pipes, but have never before heard it sung. This little video touches me deeply on so many levels: the only item missing is a picture of the Sacred Heart with a flickering electric lamp in front of it. No doubt there was one behind the camera. It is so deeply familiar—this says 'home' to me (and produced tears) when first I heard it last night.
I know that this will simply puzzle some of you. But, dear God, it is so beautiful. And beauty, I suppose, is in the eye of the beholder.
