"RaRCS" stands for "Record and Record Combined Stereo", which means that the left and the right sides of the video come from two different studio records.
In this case you can enjoy "Rapper's Delight" from the Sugarhill Gang. Theoretically these performances could have been live, but they were not. On the right side you can see the Disco Inferno performance (playback), while on the left side the Soul Train performance (also playback).
