Malcolm, may I ask you if there is any site or paper or ? which deals with the reliability/unreliability of "informants"? I know that JJ Niles is not highly regarded in this area, and I have heard an occasional mention of Ewan as fortuitously providing a tune or three. Is Anna Brown regarded as reliable? (the tunes in Bronson seem a trifle odd and she is the sole informant for several ballads). And are there others in this situation? Your guidance would be welcomed!Jon Bartlett Vancouver Ballad Group
