I do them as I see them. The guest on one Andy Griffith this morning wasn't that well known, at least not to me. I had to look her up. It was Jean Hagen. Bookie might know who she is. I didn't. She died young in '77 at 54.
Jean Hagen (August 3, 1923 – August 29, 1977) was an American actress best known for her role as Lina Lamont in Singin' in the Rain (1952), for which she was nominated for an Academy Award for Best Supporting Actress. Hagen was also nominated three times for an Emmy Award for Best Supporting Actress in a Comedy Series for her role as Margaret Williams (1953-56) on the television series Make Room For Daddy.[1]
