Looking at that list that Vic Smith posted......virtually all those songs would be ones considered 'folk' or 'folk oriented' in North America singarounds, etc.

Virtually all of them (even the traditional ones) are usually associated with one particular version.....although with something like Tom Dooley, somebody will always come up and perform and older version.   Which is great.

I'm wondering if any of those......from whatever definition you want to use, ever become 'traditional'.....and, if so, what would have to happen.

And is it possible for a song that we don't think of 'traditional' today to become traditional in the future? How?
