See Chambers's Book of Days (1879, pp. 749-750), where this carol is cited with an illustration. The carol is also in The New Oxford Book of Carols (Oxford, 1992, p. 532; with tune and detailed notes), whose version is from Ralph Dunstan's Second Book of Carols (1925). The tune is related to "Well-a-daye" ("Sweet England's prize is gone! / Well-a-day, well-a-day") in William Chappell's Popular Music of the Olden Time, vol. 1 (1859, p. 176). On gooding, see Book of Days (p. 724).
