Tim Dennehy sings a version on his CD "A Winter's Tear". He mentions hearing it from Breandan and describes his own version as "slightly adapted". He says Breandan got words and tune from Tadhg O Flatharta, a fellow Kerryman. No mention of Sean McCarthy.

In fact, some of Tim's verses are significantly different from Breandans. I'll have a listen and try to plug the gaps so far.
