DEar MJ,
The prog you were listening to lat evening was a tribute to the late Tony McAuley, a great TV music producer / singer/ musician with BBC N.I, who died of cancer in early June. The recording of Sliabh Galleon Breas was sung by Tony himself...recorded a year before he died. To optain a copy f the song you could contact
Peter Browne,
Radio 1, RTE,
Dubln 4
who might be able to help you. I do know the song was never released commercially. Hope this helps,
PJC
