I too just thought of this song, when the piano tuner came knocking at the door! I sang it as a boy soprano somewhere in the late 60s with my church choir as part of a novelty night of music. I think we changed the words a bit to match parishioners, because I don't remember "Cook's friend Emily" but rather "our friend Mrs Smith" who was the church secretary! I would love to find the sheet music, or at least a bit more info on it, such as all the lyrics.
