Manager told him to stop. Without that gimmick, he looked around the station for inspiration. Finding the 1962 edition of 'Who's Who in Popular Music' in a waste basket, he conceived of relating music trivia to the audience between the songs, which led eight years later to the development of the successful "American Top 40" show format upon which he built his later career. A decade later, KNEW was the show's Bay Area network affiliate, so Casey was again heard on "Channel 91". Morgan went by his last name while working the morning drive time at KEWB. Steele worked afternoon drive. Both had short stays, both joining Bill Drake's new "Boss Radio" at KHJ, Los Angeles. Drake's conversion of San Francisco's KFRC to the same format would bring an end to KEWB's Top 40 era. Other notable KEWB personalities included Don McKinnon, Buck Herring, "Honest" John Trotter, Art Nelson, Bobby Dale, Perry Roberts, Chris Borden, Jim Wayne, Michael Jackson, and Ken Knox. KEWB DJs Ron Lyons and Ron Reynolds returned during the KNEW years.

The station continued to struggle, as they were now competing against market powerhouse KSFO. Oldies Channel 91 In 1971, general manager Ken Gaines was transferred to KNEW from Metromedia's Cleveland station WHK. Gaines and new program director John L. Hawkins quickly evolved KNEW to a fast-paced format of adult contemporary and oldies music hosted by humorous DJs. Hawkins restored the nickname "Channel 91" and on-air elements echoing its earlier days as Top 40 rocker KEWB. KNEW recorded new station jingles using the original KEWB melody. The KNEW staff featured several KEWB veterans including Ron Lyons and Ron Reynolds, board operator Carl "The
