The melody that's coming to my head has something about a lark in it, and it's really bugging me that I can't remember what it is....

Where did the Dransfields get their melody? That's the one that sounds like "Gesu Bambino" to me.

Did Sharp publish the melody, or did he just collect the lyrics for this one? Reeves-Sharp (Idiom of the People) has lyrics only.
