It is Scottish-Gaelic I believe (Cha neil mi cinnteach!). Folktracks put out a bunch of recordings a few years back (1978 according to my copy) called Song's of the Hebrides. One series is actually subtitled Kishmul's gallery and low and behold it is the only one I don't have on hand so I can't give it to you. It is in the series though from Folktracks if you are interested. When I find it I will send it. If you could post the Gaelic name I would have an easier time finding it.
