junior partner and straight man to the veteran comedic Hull.
"Yarborough" was really the new KRLA production director, Johnnie Darin, moving to KRLA from 136/KGB, San Diego.
The name "Filbert E. Yarborough" was an inside joke.
Darin had been working under the Bill Drake (real name: Phil Yarbrough) "Boss Radio" format at KGB.
Later in December 1968, Darin began using his "Johnnie Darin" name, dropping off Hull's show, doing fill-in work for Bob Dayton on the 3-7pm show.
