Steve quotes his "own personal belief" that The Grey Cock "was put together by a quite sophisticated hand.

Jim says this "shows a distinct lack of understanding of the creative abilities of the non sophisticated".

I think we can all agree that whoever combined what seem to have originally been three separate ballads into a single coherent whole did an excellent job.

So I can only conclude that Steve and Jim (both of whom I respect for their knowledge) have different interpretations of "sophisticated".
