The well-known tune was collected by Sharp from Mary Ann Clayton in Chipping Campden, Gloucestershire on 13 Jan 1909 and published in 1911 in 'English Folk Carols'. This is an 'unusual' version, being in 3/4 time whereas most of the other collected versions are in 6/8. The tune which most people in the folk world sing seems to derive from the version collected by Maud Karpeles and Pat Shaw from Peter Jones of Bromsash, Herefordshire in 1952. The recording was issued on the LP Caedmon TC 1224 / Topic 12T 197 ('Songs of Christmas' / 'Songs of ceremony').
