The version I have is spelt Keishmul's Galley recorded by Owen Hand in 1966. I haven't played it for years but seem to remember the words are indecipherable due to the singer's pronounced Scottish accent (bloody foreigners!!).The sleeve notes say "..this song, which I first heard sung by Ray and Archie Fisher, is a rough translation from a heroic Gaelic ballad".
That's all I've got.
