I'm almost embarassed to admit we've got a copy of the 1913 edition of the English Carol Book in my library. I have it in my hand. Unfortunately the song index on our catalogue doesn't extend to carol anthologies, which is why I wasn't able to track the song down, there are just too many volumes for me to go through them all. Sorry.Jean, if you'd like me to scan it & e-mail it to you let me know. Your memory of the words is almost flawless. I'll post them later.
