There is something that has been nagging at me now for some time.As a lover of folk, bluegrass and blues music, I try to attend as many concerts as I can.More and more I am coming to realize that even established folk legends, i.e. Tom Paxton and Arlo Guthrie to name a couple, are drawing far less than full houses. We attended those concerts in Montreal and the venues were a half to two-thirds full. The weather on those dates was good and no other factors should have kept people away.Is this the same scenario in other places around the world? If so, then I venture to say that this is the last generation of folk fans.
