No wonder the Rock & Roll Hall of Fame in Cleveland is building an addition.

It’s going to need room for all of the new inductees.

The class of 2026 was announced this week. Counting the inductees, the early influences, musical excellence honorees and the Ahmet Ertegun Award recipient, 18 acts and individuals will be inducted on Nov. 14 in Los Angeles.

The honorees as performers will be Phil Collins, Billy Idol, Iron Maiden, Joy Division/New Order, Oasis, Sade, Luther Vandross and Wu-Tang Clan.

I imagine Mariah Carey’s manager having to make a call this week, saying, “Sorry, Mariah, you didn’t get into the Rock Hall this year.”

Carey: “Who did get in?”

Manager: “Everyone else.”

It wasn’t quite that bad. The Black Crowes, Jeff Buckley, Melissa Etheridge, Lauryn Hill, INXS, New Edition, P!nk and Shakira also didn’t make the cut.

I think Etheridge, Hill and P!nk all are more deserving than Sade, but I don’t have much complaint about the acts selected.

This year’s selections continue a trend that other Rock Hall aspirants should remember — If you want to help your induction chances, get someone to make a documentary about you.

The documentary “Billy Idol Should Be Dead,” now playing on Hulu, certainly didn’t hurt Idol’s chances. And I suspect the Netflix documentary “Sunday Best: The Untold Story of Ed Sullivan,” which spotlighted the variety show host’s efforts to feature African-American performers on his top-rated show at a time when those acts were ignored by most programs, is the reason Sullivan was chosen for the Ahmet Ertegun Award.

In addition to the performers and Sullivan, Latin artist Celia Cruz, Afrobeat performer Fela Kuti, alt-country icon Gram Parsons and female rappers Queen Latifah and MC Lyte will be inducted as early influences.

Songwriter Linda Creed and producers Arif Mardin, Jimmy Miller and Rick Rubin go in under musical excellence.

Sometimes those categories feel like a side door entry into the Rock Hall. This year’s musical excellence honorees are the type the category should represent — people who made significant contributions to the music industry but not household names. They weren’t the face on the album cover, but they played an integral role in making those albums memorable.

But it’s also been used in recent years to honor such artists as Dionne Warwick, Jimmy Buffett, Chaka Khan and Judas Priest. While the Rock Hall denies it, in those cases it feels a bit like, “You represent musical excellence … but not quite excellent enough to go in as a performer.”

Musical influence also is a catch-all category. Kuti had been nominated as a performer twice before, and Parsons had three prior nominations. Warren Zevon was snubbed for years and collected a single performer nomination before going in as a musical influence last year.

It has the potential to be an entertaining show, especially if Collins is healthy enough to perform and the Gallagher brothers retreat from their past derisive comments about the Rock Hall and Oasis shows up and plays live. According to the internet, Sade hasn’t toured since 2011, so maybe the ceremony will get her back on stage.

Idol, Iron Maiden, New Order and Wu-Tang Clan all are touring this year or have toured recently, so it seems likely they all will perform.

Unlike recent years, there are no plans to broadcast the ceremony live. According to the news release, the ceremony will be filmed and broadcast in December on Disney+ and ABC.

That might be for the better. With 18 inductees to get through, the ceremony might not end until Thanksgiving.
