The only live prime-time show on any of the three major TV networks in 1978, Live Wednesday was not unlike Clark's American Bandstand, with musical guests such as Diana Ross, Frankie Avalon, Bo Diddley, Connie Francis, Annette Funicello, Melissa Gilbert, Donna Summer, Bobbie Gentry and Melissa Manchester.
[1] This became a problem for the fourth episode, slated for October 18: NBC decided to bump the show in favour of Game 7 of the 1978 World Series.
(The Series actually ended in six games, so Clark and crew gathered to do the show anyway, but the network had already told its stations that NBC would air the movie "Little Big Man" if there was no baseball, and they did.)
"[2] But the variety show format was beginning to be seen as outdated by the late 1970s, and ABC owned Wednesday nights, with Eight is Enough (the eleventh-most popular show on TV that season), easily trouncing both Live Wednesday and the CBS offerings (originally The Jeffersons and the new sitcom In the Beginning, but when the latter quickly failed, CBS shuffled several programs in and out of the timeslot).
After airing a series of specials on Wednesdays in January 1979, NBC premiered a new show starting February 7, which would become on the biggest bombs in TV history: the infamous Supertrain.
