So - no new definition yet - I await with bated breath, but have been doing so for a long time! gasssssspppppppppppp

Point is there is nothing in the 1954 Definition that can't be said of all musics. Does that mean all music is Folk Music? Of course not, but, pragmatically, all music can be Folk Music if we think of music being defined by its context. This is well in keeping even with the most orthodox reading of the 1954 Definition which deals with context & derivation rather than genre. Folk as a genre is something else altogether - traditional musics & traditional idioms continue to be developed without the need of definitions as the music pretty much defines itself.   

Shouldn't concern you one way or the other as you rejected their first efforts anyway, and treated their work with the contempt you appear to treat all such, so why should the next one bother you?

Hardly contempt, old man - as this stuff concerns me, so I must engage with it in the hope that others do too. But just as the study and definition of Folklore has moved on a lot since 1954, one would hope the same might be said of Folk Music, which would appear to be the case if the ICTM (who changed their name 30 years ago) is anything to go by.
