Oh! WOW! Snuffy just sent me a recording of this song. I've been singing it for years but I use a different tune. It fits so well with the American version of "Away in a Manger". I apologise to Thomas Haynes Bayly every time I do this but it does sound good this way.
If you'd like my rendition of it just send me a PM. I'd be happy to send you my CD. If you want the original tune though, Snuffy may be able to help. Cheers, Joy
