The songs weren't actually that great musically, were they, sometimes just lists of different types of doughnuts. But we enjoyed the film, too, though my mom tends to get impatient with just slice-of-life things that don't seem to have a Point. (-;
I was trying to think of some phrase you could search on in a text corpus, or in G***** Books, that would eliminate hits for other senses, like the weight on a fishing line, or a sports shot, or whatever.
Surprisingly, the phrase 'coffee and a sinker' seemed to work pretty well, even though that may be almost too stereotypical.
https://html.duckduckgo.com/html/&q=%22coffee...(If I recall correctly, that URL won't all turn blue, I think I needed to connect the words with a different character, but it should be copyable. *edit* Rats, I've tried different things and it still isn't right. Just go to DDG and put the phrase in quotation marks. I don't know why they make their searches so hard to share.)
Maybe the O.E.D. or D.A.R.E. could also help narrow down some dates.
