When I was out walking the dog this morning I realised that I should have checked with Bronson last night (I keep forgetting I've got it now - thanks Dick!).

He divides the tunes into 4 groups - A) mainly English, B) mainly Scottish C) a pentatonic group (-4-7) D) a class of American tunes. As far as I can see his earliest is the Musical Museum version (in group B) agreeing with the above.

I presume he knew about the Caledonian Companion tune (he prints Kidson's tune, so I imagine he read his notes) but omitted it because of the lack of words with the tune.

I'll try and post the tunes from Caledonian Companion and the Musical Museum later today so they can be compared.
