Rick Dees was the smarmy morning host of Top 40 station KIIS-FM in Los Angeles during the 80s. I undid the preset of KIIS in my houehold when one morning, he played this new single by Mike + The Mechanics' called "The Living Years", and Dees went on this creepy rant where he urged all of the fathers and sons listening at that moment to call each other NOW, and mend their ways immediately! I was already listening to the (then) commerical alt.station KROQ and slowly edging toward KXLU, the college station. After that Rick Dees rant, I became a regular listener of KXLU, which changed my life.
(My family didn't know how to set radio presets on anything, so that was one of my few opportunities of dictating household policy.)
EDIT: acc. to his wiki page, he remained the host until 2004! Oh my god.
