Joe, I'm sure you'll be aware of the Roud indexes. If they all have the same Roud number it's a pretty good bet they all ought to be counted as the same song. We're just working on all the 'Unfortunate Rake'/'Streets of Laredo'/'St James Infirmary' family at the moment to see if any of them need separate Roud numbers. If you feel there is a problem with this song we can have a look at it if you wish.
