On January 31, 1971, CBS was scheduled to carry a game between the Boston Bruins and St. Louis Blues, a rematch of the 1970 Finals. The game was to begin at 2 p.m. Eastern Time, but NASA announced that the Apollo 14 lunar-landing mission would be launched that afternoon at 3:23 p.m. Eastern Time. CBS decided to air the first period of the game live, then switch to news coverage once the first period ended (at approximately 2:30 p.m. Eastern Time). At about 4:30 p.m. Eastern Time, after the launch coverage was due to end, CBS would show the second and third periods of the game on tape delay. But the launch was delayed for over a half-hour, and after the launch took place, CBS had no time to show the rest of the game on tape. The theme music that CBS employed during this period bore similarities to the song "Sounds" by Hot Butter.
