GOT IT !!!! The song was 'Wexford Lullaby' and was recorded by John Renbourn (of Pentangle fame) on his 'Traveller's Prayer' album. The Voice Squad and Maighréad Ní Dhomhnaill appear on this track and the title track. Do please try and listen to this beautiful song - it will absolutely knock your socks off! Thanks again for all the help. Ciaran.
