Rockefeller Center is getting lit Wednesday night.

“Christmas in Rockefeller Center” airs live from 8 to 10 p.m. on NBC. The 87th annual tree lighting ceremony will be hosted by “Today” show anchors Savannah Guthrie, Hoda Kotb, Craig Melvin and Al Roker.

The festive fête for the 77-foot-tall, 12-ton Norway Spruce tree will feature a staggering parade of performers including rock legends Chicago, Brett Eldredge, dancing siblings Derek and Julianne Hough, John Legend, Idina Menzel, “Glee” alum Lea Michele, Ne-yo, Gwen Stefani, Straight No Chaser, Skylar Astin and “Zoey’s Extraordinary Playlist” star Alex Newell.

In addition, Miss America 2019 Nia Franklin and the Radio City Rockettes will grace the plaza, and Jon Bon Jovi will be featured in a pre-taped performance of his new song “Unbroken” from the Netflix documentary “To Be of Service,” about military veterans living with post-traumatic stress disorder.

Viewers will also see a performance (of “Jingle Bell Rock,” perhaps?) by the cast of Broadway’s “Mean Girls,” and — in the spirit of corporate synergy — “Saturday Night Live” cast members Aidy Bryant, Michael Che, Colin Jost and Kenan Thompson will provide a little bit of jolly.

How to stream the show

In many markets, the telecast will be proceeded by a live, one-hour special starting at 7 p.m. and hosted by “Access Hollywood” co-host Mario Lopez and NBC4 anchors Stefan Holt and Natalie Pasquarella.

Starting at 6:40 p.m., New York affiliate NBC4 will air a behind-the-scenes show titled “Listen Up Live,” a hosted by Kay Angrum, on the station’s YouTube, Instagram, Facebook and Twitter social media platforms.

The lighting also will be streamed on NBC Live and Fubo.

How to watch it live

Thinking of watching the festivities in person? Bundle up — temperatures will hover in the mid- to upper-30s with a 10-to-15 percent chance of precipitation. Midtown visitors should also brace for rampant street closures starting around 3 p.m. in the area between Fifth and Sixth avenues and 46th to 52nd streets. In other words, you might be better off steering clear and watching the festivities on the small screen.

More than 50,000 multicolored lights and a Swarovski crystal star will adorn this year’s towering Tannenbaum. The first Christmas tree was hoisted in Rockefeller Center in 1931, and the annual lighting ceremony debuted in 1993. NBC first televised the spectacle in 1951.

The tree will remain lit between 6 a.m. and midnight every day through Jan. 17, 2020, though the tree will for 24 hours on Christmas Day. On New Year’s Eve, visiting hours are restricted to between 6 a.m. and 9 p.m.

When the tree makes its exodus from the plaza early next year, it will be repurposed to build homes by Habitat for Humanity.
