(To be honest, I can see how licensing six songs for one chord each would be a bit of a problem, and if Fox had made an effort to keep other music, I could have forgiven them for changing this sequence. But...)
This was the first episode produced after the show came back from hiatus, though it was probably written earlier. It is clearly an "early" episode because it's the last episode that uses the original premise of the show, which Hugh Wilson pitched to the network as "The suits vs. the dungarees" (a phrase that he actually wrote into this episode in a memorable scene). The idea that the station consisted of two factions, Mr. Carlson/Herb/Les vs Andy/Johnny/Venus, was a theme of some of the early episodes like "Turkeys Away," but was abandoned soon after this episode was produced. The credited writer is Casey Piotrowski, a real-life disc jockey.
