Bang on Skipjcack. My partner and I have long noticed the number of 'special people' drawn towards folk music. Stewarding at festivals gives you a real chance to exercise care in the community with whole herds of 'em.
To me, though, that is one of the bittersweet aspects of folk music. It does seem to give all sorts a feeling of belonging and an instant cameraderie, but it can take ages to find an excuse to dash to the bogs or the bar to escape the ramblings of some of the more 'special' amongst us!
