There really should be no argument here. Like most words in the dictionary the word 'folk' has acquired different meanings. The 1954 revised guidelines are straightforward enough for those who wish to apply them to traditional song, and I do when wearing my research hat: BUT FOLK MUSIC has acquired over the last 60 years a much wider meaning as acknowledged by the masses (some might say the 'folk' themselves) and the music industry and the folkscene at large. To deny this is to bury your head in the sand.
