Thank you Nigel
I feel that the work and ideas of many of the pioneers who helped give us so much pleasure and knowledge has been lost unnecessary in the changes that have taken place (some recent ones disturb me greatly)
An entire body of work (including your own on Dundee songs) have added immensely to to my personal pleasure and understanding of our song traditions and I feel that, rather than the 'go with the flow' approach that has been adopted, we really need to take stock of past work rather than seek out new new clothes.
This means we need to know where we went wrong, as well as what we got right - and as you touch upon, why?      
Best wishes
Jim
