Provenance is something which I and a number of friends think is of
greater importance than others think.It is absurb to credit a
'written'song to the singer,rather than the author,which is where all this bother starts.Just'cos some very capable Irishman sings 'Black
is the Colour'(and credits his source on record)does not make it an'Irish'or even a Christy Moore song.By the same token,if you've nicked a 'real'traditional song from a non source singer or group,
credit the singer you stole the song from if you dont know the 'traditional'source.And I speak as a known thief of songs,simply
because I'm incapable of writing any thing worth singing.I always
try to credit authors if known,and often singers if author is not known.
      Frank.I think you are overstating the case about bigotry.But
everybody should carry on singing anything they enjoy and the Hell with the clots who say'You cant sing that here,this a 'folk'or what
ever club or venue.Was it Burl Ives who when asked how he knew a
song was a'Folk'song said 'I never heard a horse sing it'.
