I was looking about for the "three more verses" dropped by the Oxford Book of Carols. Glad to find them still about in various places.

Others coming here comparing versions might note that where the OBC "had to alter some words for the sake of choral singing" was in verse 2:

OBC has

The name-day now of Christ we keep,
Who for our sins did often weep ;

in lieu of

For Christ's circumcision this day we keep,
Who for our sins did often weep;

For my 2 cents, while I agree that the OBC might have it right on the above substitution for the purposes of choral singing, I don't find the other verses pathetic at all. A more honest assessment might be that the liquor content is higher than they felt was appropriate. :-)

Another site with the full set (and also much of Drive the Cold Winter Away, among an assortment of "blackletter" ballads) is here.
