"Folk police"

Members of an underground musical humanitarian sect. Their main goal is to elminate subversive, intrusive and down right shite quasi-musicians - such as; Bodrahan player sand unaccomplished - oops! unaccompanied singers etc, the type well known to invoke the phenomenon known amongst real musicians as "shoe syndrome"!
For the benefit and guidance of said eucaryotic-musicians,
you will perhaps, or more likely not notice that this "syndrome" is exemplified by:- furtive shuffling and gazing at the floor, ceiling, distance, in fact anything to distract from the utter torment of your lack of musicianship!
