Jack Bannon, who played...

..."the genial and raffish assistant city editor Art Donovan on the long-running television series Lou Grant," according to his obit in the New York Times, died at age 77.

Lou Grant was "a newspaper drama spun off from The Mary Tyler Moore Show, which starred Ed Asner in the title role and was seen on CBS from 1977 to 1982."

I remember watching that show and really liking it.
