To word it another way Ray. Going by what I've read here for example, if anyone asked about "The Recruited Collier", we should be answering this is AL Lloyds reworking of Jenny's Complaint about a pressganged farmworker. rather than "this is a traditional song about colliers". It's not a judgement on the later work or a suggestion that there is anything wrong with a derived work. It would merely be the factual information someone wanting info on the song might require.
