Everyone loves a comeback story. And this year, Broadway will be celebrating one for the ages.

“Merrily We Roll Along,” a Stephen Sondheim show that has long been one of musical theater’s most storied flops, will cement its long-sought redemption on Sunday by winning the Tony Award for best musical revival, according to my annual survey of Tony voters.

This week I have connected, by phone or by email, with just over a quarter of the 836 Tony voters, and asked how they were voting. In a season in which lots of new musicals have admirers but none seem to have fully satisfied industry insiders, that race is tight, as are some of the key acting categories.

But “Merrily,” more than any show since “Hamilton,” has won over not only the ticket-buying audience, which has made this production a significant hit, but also the group of producers, investors, writers, actors, designers and others whose work or volunteer lives are so theater-involved that they have qualified as Tony voters.

The survey is not a scientific poll; some voters haven’t even cast their ballots yet. For the actual winners (and some song and dance, too), tune in Sunday for the awards show, which starts at 8 p.m. Eastern on CBS and Paramount+ with Showtime. A preshow with some of the awards will stream on Pluto TV starting at 6:30 p.m. Eastern, and we’ll be live-blogging all evening at nytimes.com/theater.

Until then, here’s a look at what those surveyed are indicating.

“Hell’s Kitchen,” the Alicia Keys musical, is doing quite well: good reviews, lots of media attention and the strongest sales of any of the season’s new musicals.
