Once upon a time it was a matter of paying one's dues - you could do contemporary songs but it was de rigeur to do a "folk" (Karpeles definition) song or two to show you were not just a popster manque (I wonder where the acute accent is on here).

Then I found fewer and fewer people even nodding the the "roots" of what we were doing, and so I started doing more and more of them...

I also found the horse definitioners so infuriating...
