I’m just throwing out some works I’ve found that seem like they could use improvement / clarification. I poked at them long enough to realize it was going to take time that I’d rather use on other things to figure it all out. Not quite a request, but if someone feels motivated to work on them…
Little Sadie, Clarence Ashely (+ Bob Dylan) vs TJ Arnall versions and credits
Creole Belle, Mississippi John Hurt is usually credited but there was an earlier version
Little Joe, usually credited to A.P. Carter, sometimes Bill Monroe, but has existed since at least 1866
