There was no opening credits music at the beginning. The closing credits, however, featured the Second Movement of Ludwig van Beethoven's "Ninth Symphony", played on a classic 1952 recording by the NBC Symphony Orchestra conducted by Arturo Toscanini.
Tom Lehrer mentioned the show in his song "So Long Mom (A Song For World War III)" from his 1965 album "That Was The Year That Was": "While we're attacking frontally/Watch Brin-k-ley and Hun-t-ley/Describing contrapuntally/The cities we have lost."
The signoff for each program was simple yet became world famous and iconic. David Brinkley: "Good night, Chet", Chet Huntley: "Good night, David, and goodnight for NBC News".
Was the basis for "NBC Nightly News" which started after Chet Huntley retired.
The opening pre-credits sequence was almost always Huntley saying "Chet Huntley, NBC News, New York", followed by Brinkley's "And David Brinkley, NBC News, Washington".
