There seems to be an attitude from some quarters that 'folk' songs emerged from the ether many centuries ago and were not actually written by anyone. That or they have been subject to the 'folk tradition', which to my mind means badly misheard by some member of the audience, who then rewrites the song and passes it off as his/her own. I sing 'trad arr.' as well as my own stuff. A good song is a good song, an old song isn't always....
