I searched Mr Google to no avail. The mention of macaroni (Mr Kraft sold lots of their Mac and Cheese in the Second World War) offered some hope, but it gets lost in the clutter of 'macaroni' in its non-food use (stuck a feather in his cap, etc). It might be worthwhile to get back to your requester and see if any other pieces of verse come to her memory. I think there is insufficient info to locate the song. I do however suspect the dad may have made a few lines up, and coupled with a memory that's perhaps become a bit vague over time, well, chances aren't too good in terms of locating the song. Sorry I can't be of help.
