I've just been reading all these comments and felt obliged to add my bit.
I was just looking up the chords and lyrics to some old Corries songs and came across this site.
I heard the Corries sing Shoals of Herring and Hills of Ardmorn on an old radio about an hundred years ago and haven't been able to get the sound out of my head since then. I've done a lot of searching over time and have just resorted to the internet to get the real words... I copied the ones I have by playing an old tape over and over until I caught the words. I found the chords myself. Let me just say that for me hearing the Corries' beautiful harmony's and the passion they put into their music grabbed me all those years ago and I've just never forgotten it. That's all.
