Considering folk is more than traditional, collecting is more than sitting fascinated by the tall tales of old people. Cataloguing is collecting in the academic sense, so stop splitting hairs. Sixty years before Child was born wasn't very "modern" unless you know different Jim.

Folk is entertainment. Entertainment is subjective. Jim might not wish to sit through a folk rock concert and I'll pass when it comes to hearing an old asthmatic lass from a caravan, as would most people, but

Thats all folk.
