King's "Drum Major Instinct" sermon, given on 4 February 1968, was an adaptation of the 1952 homily ''Drum-Major Instincts'' by J. Wallace Hamilton.

King encouraged his congregation to seek greatness, but to do so through service and love. King concluded the sermon by imagining his own funeral, downplaying his famous achievements and emphasizing his heart to do right.

Carl Sagan was a Brooklyn-born American astronomer, scientist, cosmologist, astrophysicist, astrobiologist, author, educator, and theorist. He was interviewed by CNN's Ted Turner in 1989 on many topics and talked about how humanity needs to evolve beyond greed and war.

Ted Turner then asked if Carl Sagan if he was a socialist.

Carl responded by talking about the US's obsession with wasting money on defense projects instead of investing in its people, ending with "we are using money for the wrong stuff."

Hymn of the Nations, originally titled Arturo Toscanini: Hymn of the Nations, is a 1944 film directed by Alexander Hammid, which features the Inno delle nazioni, a patriotic work for tenor soloist, chorus, and orchestra, composed by Italian opera composer Giuseppe Verdi in the early-1860s. For this musical work, Verdi utilized the national anthems of several European nations.

During the post-war Red Scare, the US government crudely censored "The Internationale" (the then-anthem of the USSR) out of the film. The version continued to be released without any acknowledgment of censorship. The uncensored version was thought to have been lost until a print was rediscovered in Alaska.

This rediscovered print has been digitally placed back into the film (at 13:08) to give an idea of what it would have originally looked like before it was censored. The audio is from a vinyl recording which was never censored.

This is a mashup of two versions of the anthem: State Anthem of the Soviet Union by the Bolshoi Theatre Choir and by Moscow Philharmonic Orchestra, conducted by Kyrill Kondrashin
