Because the technical strike that crippled last week's broadcast had not been resolved before going to air, a number of technical glitches occur during this broadcast: there are a few bad camera switches in "Purino Rat Chow"; the title screen appears right after the videotaped footage of the skiiers wiping out in "The Claudine Longet Invitational", and the title screen for "Great Moments In History" flickers onscreen before the text epilogue appears. Additionally, the camera and lighting work, especially during the music performances, still looks unpolished: shot composition is awkward and the lights dim and then overbrighten at one point during Phoebe Snow's second number.

During the live broadcast of this episode, it turned out that John Lennon and Paul McCartney (who confirmed this in separate interviews a few years later) were hanging out together in Lennon's Dakota apartment watching the program, turned to each other, and considered going down to the studio to collect the check and perform live on TV; they decided that they were too tired to go down and perform, so they stayed home instead.
The incident (along with several other encounters between the two surrounding this time period) were fictionalized into the 2000 VH1 made-for-TV movie Two of Us.
