One thing that led to endless confusion is that in the Sixties, "folk groups" such as the Kingston Trio, Peter Paul and Mary, The Limeliters, The New Christy Minstrels, et al recorded a lot of songs that were newly written--not traditional--or derived from non-traditional sources (e.g., They Call the Wind Mariah from a Broadway musical, Try to Remember from an Off-Broadway musical, and many others) and people assumed that because they were sung by "folk singers," they were (are) folk songs. That confusion is still rampant.
