Way back in a thread called A Real Folksinger, I wrote the following:

A real folksinger understands that folk music is not a genre. A real folksinger understands that any song can be a folksong. A real folksonger knows there is no such thing as singing a folksong wrong. If a real folksinger forgets the words, he/she makes up new ones on the spot. If a real folksinger can't quite remember the melody, he/she invents one that fits his/her own vocal style, perhaps flatting a 7th here, jumping an octave there, or changing a major key into a mountain modal.

I stand by those words.
