Some of the scenes I remember fondly with music. Les Nessmon putting on a curly wig while "Hot Blooded" is playing. Johnny Working the graveyard shift half asleep while Linda Ronstadt is playing. The last time I saw that episode they had cut some of that out.
BTW. Has anyone ever noticed a couple bloopers in the pilot episode. When Johnny rakes the needle across record of "Your Having My Baby" by the Halelujah Tabernacle Choir, the volume is turned down but you can still hear the needle scrape. When he starts the rock and roll record on the other turntable he bumps the turntable arm and the needle is riding on the label near the center hole but you can still hear the music playing. In the first episodes the map behind Jennefers desk says "WKRP 50,000 watts" but in later episodes it says 5,000 watts.
I also love the original opening that says, "...and the Senator, insisting that he was not intoxicated, could not explain his nudity"
