Butch Patrick, who played Herman and Lily Munster's son, Eddie. The on- and off-screen chemistry of De Carlo and Patrick was a success story of 1960s television. After the show's cancelation, like everybody else (in the cast), he also distanced himself from her, to form his own rock band Eddie and The Munsters, years before he either kept in touch or have visited her, during De Carlo's final years, who also said in a 2013 interview with Rockcellar magazine: "Yvonne would be a maternal influence. She'd be a mom because my mom wasn't around so she'd be a matriarch, not only on the show but when I'd see her outside of the makeup on Mondays and Tuesdays. Once in a while she'd bring her kids down to the set." Then, in a 2017 interview with ComingSoon.net, he also said about the Director, who had ever recalled if his TV mother was hiding tiny portions of dialogue, around the set, attaching to props to help jog her memory, where it was added to her performance: "No, not in The Munsters she wasn’t doing that. Maybe later in life. Because sometimes your memory starts slipping on you. But that’s a great idea, actually! I’ll have to remember that!" He also had said if he had ever kept in touch with his on-screen family, after The Munsters was canceled, esp. DeCarlo herself, was: "No, after the show ended, everyone went their own ways. But in the early ’80s, I contacted Al Lewis and we became friends and I started attaching myself to the Munster name and brand. And then 10 years after that I started talking to Yvonne. I was actually a guest on The Vicki Lawrence Show where I was this surprise guest brought out for Yvonne and after that we became friends. I started going up and visiting her and she was somewhat of a recluse, living in North Los Angeles and I introduced her to this guy in Hollywood who would send her care packages, movies to watch and sort of get her back in the loop of Hollywood."
