On Tuesday, October 19, 1971, CBS offered a Hawaii-themed (and recorded) edition of The Glen Campbell Goodtime Hour with guest Jack Lord, an episode of Lord's Hawaii Five-0, and an all-new Cannon with a young(er) Vic Tayback!
ABC began at 7:30 with guests Billy Dee Williams and Robert Foxworth on The Mod Squad, then a made-for-TV movie called Suddenly Single. IMDB says, "A newly divorced man finds it difficult to get used to the single world." Check out the cast behind star Hal Holbrook: Margot Kidder, Michael Constantine, Agnes Moorhead, Barbara Rush, Cloris Leachman, Harvey Korman, David Huddleston, and more! Marcus Welby closes the evening on ABC with part 1 of a crossover with Owen Marshall.
Perhaps my personal favorite single program is over on NBC, not the new Ironside at 7:30, nor an episode of The Funny Side with Gene Kelly at 9:30. The draw for me is All-Star Circus at 8:30.
Ed McMahon hosts an hour of circus highlights filmed at Circus Benneweis in Copenhagen, Denmark. In addition to his hosting duties, McMahon, a former Philadelphia TV clown, dons his costume and makeup to perform (with three other clowns) classic pantomime routines between such international acts as Eric Brenn and Taras Bulva and His Seven Tigers.
