Flying vampires, vogueing cats, a sweet transvestite and a Celine Dion send-up. Also: flashes of the past, via the singing missionaries of “The Book of Mormon,” the publicity-seeking jailbirds of “Chicago” and the striving hoofers of “A Chorus Line.”

The Broadway season that just ended was sparser than many, especially on the musical front. But the producers of the 79th annual awards ceremony are hoping to turn that scarcity into an opportunity, packing the three-hour broadcast with nostalgia alongside newness.

The televised portion of the ceremony, hosted by the pop star Pink, begins at 8 p.m. Eastern on Sunday, broadcast on CBS and streaming on Paramount+. There’s also a preshow segment, streaming on Pluto TV (a free service) beginning at 6:35 p.m. Eastern, at which awards for some of the design and other categories will be handed out.

My colleague Melena Ryzik spent time with Pink last week, and told me that Pink has been getting advice from some of her famous pals, like Neil Patrick Harris, the Tony-winning actor and a four-time host of the show, as well as the comedic performers Amber Ruffin and Kerri Kenney-Silver.

Her opening number, choreographed by Sarah O’Gleby and written by Benj Pasek, Justin Paul and Mark Sonnenblick, will feature over 170 Broadway performers.

Pink promises to do some of her signature acrobatics — though not as much as in her own arena performances. (Radio City Music Hall, the venue for the show, is not built for it, she said.) Mostly, she just wants to be funny.

“None of this was on my bingo card,” she told Ryzik. “And I’m here for it; I’m committed, I’m all in. I just want to be a part of the celebration. I’m glad I get to be.”

The preshow ceremony will be hosted by the actors Laura Benanti and Tituss Burgess.

During the telecast, there will be moments noting big anniversaries for four very-well known and historically important shows: “Chicago” and “A Chorus Line” (both 50), “Rent” (30) and “The Book of Mormon” (15). Queen Latifah will be featured in the “Chicago” tribute; Rachel Zegler will honor “A Chorus Line”; and Leslie Odom Jr. will sing a song from “Rent” during the In Memoriam segment. For “The Book of Mormon,” the stars of the original cast will reunite.

There are lots of competitive awards categories. Particularly close: best musical revival, with voters split between two very different contenders: “Ragtime,” an epic show about America’s promise and perils, and “Cats: The Jellicle Ball,” a radically reconceived take on the now-and-forever musical.

Other close contests include best actor in a play, where John Lithgow and Nathan Lane are leading the pack, and best play revival, where “Death of a Salesman” appears to have an advantage over “Oedipus.”

The race for best new musical — traditionally the one with the most box office impact — features four contenders: “The Lost Boys,” a teen vampire musical with a pop rock score, based on the 1987 movie; “Schmigadoon!,” a comedy about a couple trapped in a village whose residents sing, dance and generally behave like characters from Golden Age musicals; “Titaníque,” a spoof of “Titanic,” but with Celine Dion as one of the characters; and “Two Strangers (Carry a Cake Across New York),” a charming rom-com. My annual voter survey suggests that “Schmigadoon!” is likely to win, but an upset is always possible.

In the best play category, “Liberation,” a Pulitzer-winning drama about a 1970s women’s consciousness-raising group, looks likely to win over “Giant,” about an antisemitism controversy confronting the children’s author Roald Dahl; “The Balusters,” about a fractious neighborhood association; and “Little Bear Ridge Road,” about two lost souls in rural Idaho.
