I liked Bill D's short list, above. One thing about The Two Sisters is that there are versions that have evolved so far from each other that they have barely a line in common, yet you can still tell instantly that, in some important way, they are the same song. Also, it's easy to miss a recording of that song if you're not aware of all the different titles under which it is recorded.

Another one that has been recorded under many different names is The Golden Vanity.

My own record collection leans heavily towards the American and may feature more recordings of John Henry than any other single song.
