35 years ago today, WKRP in Cincinnati debuted on television. That show is one of the things that inspired me to get into radio. I absolutely loved it.
The opening theme song became famous, but to me the song that really rocked was the one they played over the closing credits every week.
According to Wikipedia, the closing theme was written by an Atlanta musician named Jim Ellis, who also wrote incidental music for WKRP. He didn't have any lyrics for the tune yet, so he sang a bunch of gibberish to give a feel for the song. Hugh Wilson, the series producer, decided to use it anyway because it would be a humorous commentary on the incomprehensibility of many rock lyrics. I think he had a point.
