See the KOST TV commercials when KOST was battling KBIG to win the beautiful music ratings in Los Angeles. As a favor to KOST beautiful music Program Director Fred Seiden, Johnny Mathis not only made an appearance as an actor, but sang a custom song as well! Unfortunately, the commercial never aired, because - by the time it was finished - management had already decided to change KOST's format from beautiful music to adult contemporary. Interestingly, programmer Jhani Kaye - who transitioned KOST from beautiful music to AC - actually mixed the audio for the beautiful music commercial, not realiziing that he'd be taking over the programming a couple of weeks later!
