Let me take it a step further. If you're performing in public, it's nice if people can understand the words. It's not nice if you take half the show with inane drivel while you're trying to tune. It's not a good thing to follow a long ballad in Em with another long ballad in Em.

Folksingers don't have to act or sound like anything but folksingers. But it would be nice if they looked and sounded like goodfolksingers.
