Folk music, as with jazz, rock etc, draws people from a broad spectrum of society, some of whom are clearly well off while others struggle to make ends meet. It just seems to me that little goodwill is likely to be engendered by accusations of tightfistedness when its root cause might be a basic shortage of funds. The golden rule applies, IMHO.
On a lighter note, WLD, I had thought I was alone in boggling at the flashy kit wielded by some floorsingers. But hey, if it does the biz for them then it's all to the good. Two pints of neck-oil does it for me, but I'm only a singer. :-D)
