One thing I found amusing about the TV show picking the call letters WKRP is that MTM said the calls weren't close to any
actual station broadcasting in the Cincinnati area.
However, that's not true. WKRC AM and WKRC TV, plus sister WKRQ were already well established in the market.
I don't remember where I heard that about MTM saying the calls weren't close to any other Cincy stations. I may not have that totally correct.
Another thing, on ME-TV Sunday night they broadcast 2 hours of WKRP episodes. The music isn't totally original, and that's disappointing. Les dancing to Hot Blooded was classic, and that was changed to meet royalty requirements. And Mr & Mrs Carlson dancing to Thank Heaven for Little Girls was also changed. But it's not as bad as those DVD sets, some of the music is actually right.
I found a blog that has some links to videos of the actual shows, with music intact.
