There's always the risk that an old, forgotten thread revived after nearly 7 years in the tomb will attract irrelevant replies to things said long years ago.

For the benefit of 'Muttley' and 'Guest', I will repeat what I have said before. "Scotch", though old-fashioned and well on its way to obsolescence, is still perfectly correct usage as an alternative to "Scots" or "Scottish". Although mostly used nowadays as an adjective in compound forms ("Scotch whisky", "Scotch mist" etc) there are still a good many older Scots who are perfectly happy to use it as a general adjective as well as an abbreviation for whisky. Though there will inevitably be people who make a fuss about it (that is nothing new), they do risk making themselves look more ignorant than those they criticise.

See any standard Scots dictionary if you don't believe me.

Now, do either of you have anything helpful to add on the subject of the Loch Tay Boat Song?
