Sam Riddle, the popular Los Angeles “Boss Radio” deejay of the 1960s who went on to produce the Ed McMahon-hosted TV talent show Star Search, has died. He was 83.

Riddle died Monday at his home in Palm Desert after a battle with Lewy body dementia, a publicist announced.

In an era when radio disc jockeys exerted huge influence on sales and pop culture, the Texas native started out in L.A. radio on KRLA and jumped to KFWB before landing at KHJ-93, where he became one of the founding jocks behind the “Boss Radio” format.

By virtue of his influence in charting hits, he appeared as a race announcer in the Elvis Presley starrer Clambake (1967).

On television, Riddle hosted 9th Street West and Hollywood a Go Go, which showcased such acts as The Rolling Stones, James Brown and Sonny & Cher. The recent HBO documentary Tina showed him introducing Ike & Tina Turner before their first big TV appearance.

On the syndicated Star Search, which ran from 1983-95, Riddle gave career breaks to such future stars as Britney Spears, Justin Timberlake, Usher, Dave Chappelle and Christina Aguilera.

Riddle was born on Dec. 12, 1937, in Fort Worth, Texas. After his parents, Robert and Juanita, divorced, his stepfather, Sam Hand, who owned a dairy farm and advertised in local radio, helped get Riddle his first job on the radio at age 16.

He served in the Air Force Reserves during the Vietnam War and worked as a deejay for stations in Arizona and San Diego before coming to Los Angeles.

Riddle’s producing résumé included the shows Boss City, Aloha a Go Go, Get It Together (with Mama Cass), Almost Anything Goes, The Lou Rawls Parade of Stars, Supermodel of the World, Out of the Blue, It’s Showtime at the Apollo, Livin’ Large and The Ultimate Poker Challenge.

He also oversaw the early creation and production of specials and series for Telemundo and Univision and managed acts for such labels as Sony/BMG and EMI Latin.

Survivors include his wife of 54 years, Adrienne; children Scott and Courtney; and grandchildren Miracle and Garin.

The Kid LAROI has amicably parted ways with his management at Scooter Braun’s SB Projects and is now being repped by Adam Leber at Rebel Management, a source familiar with the situation tells Billboard.

The 18-year-old Australian-born rapper-singer LAROI had been managed by Braun’s SB Projects since June. He had previously been at Grade A Projects.

LAROI’s track “Stay” with Justin Bieber — another Braun client — is currently the No. 1 song in the country, topping the Billboard Hot 100 for six weeks since its July 9 release. The song has also topped topped Pop Airplay, Radio Songs, Streaming Songs, the Global 200 and the Global 200 Excl. U.S. charts. His previous single, “Without You” with Miley Cyrus, reached No. 1 on Hot Rock & Alternative Songs and Adult Pop Airplay charts.

Since LAROI released His F*ck Love EP on July 24, 2020, as a 15-track album that debuted at No. 8 on the Aug. 8, 2020-dated Billboard 200 albums chart, he’s continued to reissue it as subsequent volumes with additional tracks — and great success. It was reissued on Nov. 6, 2020, as F*ck Love: Savage with seven additional tracks and bounded 81-3 on the Nov. 21, 2020, Billboard 200 chart. It was then reissued a third as F*ck Love: 3 on July 23 and again for a forth time as F*ck Love: 3+ on July 27, adding seven and six tracks, respectively, including “Stay,” and finally topping the Billboard 200. The album’s total tracklist now stands at 35.

The Kid LAROI was nominated for best new artist at the MTV Video Music Awards, which were held on Sept. 12. MTV revealed that he was one of the top two finalists for that award, which went to Olivia Rodrigo. Both artists are expected to land Grammy nods for best new artist, among other categories.

Leber — who also manages Lil Nas X, Labrinth and until last month Miley Cyrus — launched Rebel in April in conjunction with Live Nation. He had previously been a partner at management conglomerate Maverick, which he co-founded in 2014 alongside other music management heavyweights Clarence Spalding, Larry Rudolph, Guy Oseary, Gee Roberson, Scott Rodger, Cortez Bryant, Ron Laffitte and Caron Veazey.

Braun and Leber did not respond to request for comment at time of publishing.
