What's My Line? with Hal Linden as the Mystery Guest (1973)

About a year and a half before his role in my choice for the greatest sitcom of all time, Barney Miller, Hal Linden appeared as the Mystery Guest on this episode of What's My Line? from 1973 hosted by Larry Blyden. Elaine Joyce and Tony Roberts join our regulars of Soupy Sales and Arlene Francis in this episode.
