Brenda Vaccaro was Rossane Barr before Rossane was. Raspy voice, slouchy manner. She was also simliar to Suzanne Pleshette, except, of course, Suzanne was a knock out back then, and her earthiness was the perfect foil for Bob Newhart’s nerdiness.
I have the DVDs of the Bob Newhart shows with Pleshette.
What is jarring about the series is how Bob’s character treated her. Viewed with today’s cultural eyeballs, he was a chauvinist, insulting, demeaning husband. It’s amazing to watch now.
