Stephen Knight, editor of the Forresters MS, makes no real claim for the two Pinder of Wakefield texts that would place them as early as 1557. Although a ballad of that name was entered in the Stationers Register in 1557-8, it does not survive in print; both of the Forresters examples are likely early-to-mid 17th century, though Knight does suggest that the second may be, more or less, the 16th century text. Possible, but conjectural only.

I had thought that the tune Wakefilde on a green had been posted here (perhaps even by me) but I seem to be mistaken.
