"Boss Radio"In April 1965, programming consultant Bill Drake crafted KHJ's top-40 format. Drake hired program director Ron Jacobs, who had created formats in Hawaii and California. The format featured a restricted playlist and restrained commentary by announcers (although a few, such as Robert W. Morgan, Charlie Tuna, Humble Harve and The Real Don Steele, were allowed to develop on-air personalities). Other DJs from 1965-68 included Roger Christian, Gary Mack, Dave Diamond, Sam Riddle, Johnny Williams, Frank Terry, Johnny Mitchell, Tommy Vance, Scotty Brink, Steve Clark, Bobby Tripp, Tom Maule and Bill Wade. Part of the format, known as "Boss Radio", were jingles by the Johnny Mann Singers.
