Maybe too many of the current generation of folkies have heard too many crap versions of classic songs like Kumbaya & Streets of London to ever want to hear them again.
But don't condemn the songs to oblivion & let the younger generation reject them unheard because people have tired of them.
For me, there will always be an appreciative smile when I hear Joan Baez singing Kumbaya or Ralph McTell singing Streets of London.
And bluntly, if you can't equal the performance or the writing, you really lack credibility when you take cheap shots as certain people have
Just my opinion
