Brian, like you I am a singer not a scholar, I am also interested in origins of songs, however if song is a good song or it was written by Lloyd and not traditional it does not put me off singing it, my reason for singing a song is the merit of the words or tune its origins are of interest to me but very much secondary.
I do not like your description "charactristic good grace",I did not single out any one person a a wanker, but all those people who appear to wish to discredit Lloyd and concentrate on his negatives rather than positives are in my opinion wankers, it is fairly well established as to which tradtional songs Lloyd probably wrote, but we will never be 100 per cent sure.. as he is dead, far better in my opinion to be grateful to Lloyd for improving the repertoire than going on a detective mystery which in my opinion cannot be solved, however if you wish to spend your time on that, thats your business, mean while I will look at Lloyds positives and enjoy the songs he "collected" chacun a son gout.
