"One of the problems of being old is" becoming old and still not knowing what folk/Folk is.
I've given up reading what "comes up again and again and again and again etc." and come to the conclusion I'm never going to find out.
When the word 'folk (music)' was first coined, it applied to a specific ideal, the word is now redundant and to keep applying it the the multi genre of modern adaptation of music is totaly inept.
