I still don't buy the downplaying of "You'll get a belt from your da." I don't think it's advocating child abuse (and I don't think Cilla Black took it as that), but it certainly seems to me to tell the story of the dismal situation a young mother with a husband who spends a lot of time drinking, and is likely to get violent when he gets home.
At least, that certainly seems to be the literal meaning of the words.
