Two points: the first post to this thread gives the DT versions. I posted the "Wild Boar" thread (and this should be added to DT if some Joe-clone with the proper authorization is reading this) from the singing of Bob Webb, learned from him in the mid 70's.
The second point: (and far more intriguing). Child worried long and hard over how to organize his collection, and wrote several times to Grundtvig in Denmark asking for his suggestions (since Grundtvig was the Danish "Child" who had pulled together and organized all extant Danish ballads in a fashion similar to Child). Grundtvig suggested Sir Lionel (= Bangum) as Child 1, a representative of the class of heroic ballads in interleaved couplet form, which he thought the oldest. His suggested list is Appendix B to Sigurd Hustvedt's "Ballad Books and Ballad Men" (Harvard UP, 1930). Appendix A is the complete correspondence between Child and Grundtvig, and is a great read.
