Too pricey for me as well, but no doubt, it will be a good bit of insight. Please do report back to us. Powerpoint for the discussion is unnecessary.
From what I researched on it, my take is a kind of free spirit, hippie-chick, in revealing waitress costume, falls in love with handsome restaurant owner. She didn't know of the Kingston Trio at the time. She goes from idealistic San Francisco flower child to magically enchanted wife of generous rich celeb guy. Nick is closing out his business life as a performer and they marry and go to Oregon. Eventually, they split, but she's happy for him.
That's my impression.
