Once again the same old boring arguments and problems arrive when people start to put artificial hard and fast boundaries between music genres. Most, perhaps all, music genres need to be considered in terms of Venn diagrams. Much of it is guided by opinion and everyone is entitled to that. We're a democratic country so if the majority of people regard Jimmy Shand as folk should we accept that? I use the word 'folk' in many different ways as I'm sure most people do. If I'm exchanging ideas with a professor of music I'll probably use the 54 descriptors. If I'm asked to describe a 'folk' activity to a newcomer I'll probably use something much more general. If I'm asked to pigeon hole the song 'The Country Carrier' I'll probably say it was written in the 1860s by Harry Clifton, but by 1900 it was being collected as a traditional folksong. No problem.
