Sinister Supporter

I've seen them giving warm appreciation to all shades of singer / songwriter schlock, piss-poor pop covers and Bob Dylan sing-a-longs, but bristle with barely repressed hostility when someone has the temerity to sing an unaccompanied ballad of a greater duration than 5 minutes.

I'd just like to say that, in getting on for forty years on the folk scene, I have never encountered anything like that.
