When both Johnnie Darin and William F. Williams joined KRLA in December 1968, the rumor was that Williams would do a "tracked" morning-drive show, and that Darin would do a "tracked" afternoon-drive show joining the OTHER "tracked" shows, Roy Elwell 10-3pm, and Rebel Foster 7-Midnight making KRLA all-voice tracked all the time. It made economic sense.Instead, new PD Doug Cox instead decided to DUMP the Shaefer voice tracking units, as soon as he could, and go "all-live."
Darin never did get the rumored PM-drive shift, but for a week in December 1968, he DID jock the 3-7pm shift "live" for vacationing Bob Dayton, which led to some of the speculation back then.
Here is "what if" demo artwork from that Doug Cox-era.
