I think my elder daughter has the recording- I used to have it but I can't find it. The recording is still available from some dealers, but has been discontinued. I'll ask her, and try to post, if no one comes up with it in the meantime.
(Not sure that it is the Engel song. My ears hear something about night)

Strange it doesn't come up in a google search if it is a folk song popular enough for that recording.
