I didn’t watch “WKRP in Cincinnati” (1978 – 1982) when I was a kid; it was a show for adults. I loved the theme song just as much as anyone else, though.
This was just meant as a catchy tune for the show’s opener — but it was such a cool and popular soft-rock number (performed by Steve Carlisle), that a full-length version was released as a singe in 1979. It reached number 65 on the Billboard Hot 100 Chart in 1982.
