I used to sing this Andy Mitchell song a long time ago, learned it by ear - I think from a tape - - pronounced Calum Mhor /Mor(Gaelic?) I would need to listen to it again to recall the words - - but I think I was given it by Sheena Wellington? or- maybe it was on Sheena's (cd? cassette? - the one that had Last of the Great Whales on it)
Powerful song.
