Folkie Dave,take melodeon boys advice.
Manifolds point[asIunderstand it] is the text is only a skeleton,and that with modern technology[the computer perhaps]theycan be circulated far quicker and over a wider area,than when they were passed on orally as in Patersons time.
However he contradicts himself IMO by stating that they only belong in certain places,and shouldnt be sung by schoolteachers or hillbilly addicts[hillbilly music is folk music ClarenceAshley Roscoe Holcomb,Jean Ritchie.
HE SAYS.the wrong people are those who are bent on taking it out of its natural surroundings.
So on the one hand he says he hopes the songs will leave the page and pass into oral circulation over a wider stretch of country than the old method could cover,.but then he says only certain people can sing them,and then only in their natural surroundings[whatever that is][does that mean only miners can sing mining songs]that means Ewan Maccoll shouldnt sing Springhill disaster.
the last line is pure boloney,people will sing the songs wherever they like, regardless of their occupation,because they are the songs of the folk or people.
If you dont want certain people to sing the songs you shouldnt publish them in a book.
