NEW YORK — Last year at the Tony Awards, a rabid interest in “Hamilton” stemmed a three-year slide in viewership. This year, there’s a new host, an old home and hope that a starry list of celebrities can cure the post-”Hamilton” hangover. None other than “Hamilton” creator Lin-Manuel Miranda will be on hand to help the transition.

Kevin Spacey, the Oscar-winning “House of Cards” star who has a Tony of his own, will be host of the telecast Sunday from the massive 6,000-seat Radio City Music Hall. With a foot in both Broadway and Hollywood, Spacey brings glamour and acting chops to the job.

He declined earlier this week to reveal what he plans to do, other than saying, “Everything’s on the table.” When pressed, Spacey didn’t buckle. “You’ll just have to tune in and see,” he said.

Those watching will see musical numbers from nine new and revival musicals, including “Bandstand,” “Come From Away,” “Dear Evan Hansen,” “Falsettos,” “Groundhog Day The Musical,” “Miss Saigon,” Josh Groban and the cast of “Natasha, Pierre & The Great Comet of 1812,” “Hello, Dolly!” and “War Paint.” There will also be a performance by two Tony Award winners from last year — Cynthia Erivo and Leslie Odom Jr.

But one thing they won’t get to hear is Bette Midler sing after talks failed to land the diva, who’s starring in a hit revival of “Hello, Dolly.” In other sour notes, the thriving and popular “Anastasia” didn’t get a slot, despite its draw with young people, particularly women. Nor will the musicals “A Bronx Tale” and “Charlie and the Chocolate Factory,” despite their box-office popularity and the inclusion of some other shows that are struggling.

Each of the musicals picked for the show has been busy fitting in Tony rehearsals between matinees and evening performances. The performers from “Come From Away,” a feel-good Canadian musical set against the horror of 9/11, played their regular Thursday-night show and then got into buses to go to Radio City for a run-though for what they’ll do at the Tonys.

It marked actress Astrid Van Wieren’s first time inside Radio City and she and her castmates took time to soak it all in, including watching Spacey rehearsing.
