"WAV's argument that songs with a known author can't be trad"...I stand by that, Volgadon. And, for another e.g., Ewan MacColl's songs will never be trad. - because (C), (P), modern technology, etc., will not allow the fact that they are his to be forgotten, even if some mistakenly think they are singing a trad. song or don't show due respect.
