Roger Roger was born 1911, and died 1995. The French composer produced a large range of library music used in film and television. He was a pioneer of electronic music, using the Moog synthesizers that first appeared in the late 1960s. He used many different aliases, including Cecil Leuter (a name he used especially for electronic scores). "Videotronics no.3" is also used in End Of Eternity. Another track by Roger appears in The Infernal Machine.
Georges Teperino was born 1912, and died 1994. The French musician was another pioneer in electronic music. He usually recorded under the name Nino Nardini, and was a close friend and collaborator of Roger Roger. "Cosmic Sounds No. 1" is also used in End Of Eternity. "Cosmic Sounds No. 3" is also used in The Last Enemy, but slowed down.
Giampiero Boneschi (born 1927, died 2019) was an Italian conductor and composer, working with many Italian record labels and RAI, the Italian broadcaster. This track is heard playing when Zoref enters the solarium; it was released on the 1973 Chappell record "Sounds Electronic".

Some prints of this episode (such as the US laserdiscs) show an on-screen microphone top left during the opening shot of Koenig and Bergman. On the DVDs (all versions), the frame is zoomed in so the microphone is not seen. Thanks to James Poll.
