I did a poor job nominating Willie of Winsbury, which is in as "Willie of Winsbury (Child 100)--Anais Mitchell" because that's the version I'm familiar with, but I really meant "tell me more about Child Ballad 100" and would be happy for it to go on the list with Sir Patrick Spens, which is also a Child Ballad. There's nothing particularly Anais Mitchell about it except of course her music.
