This year's Christmas tree lighting at Rockefeller Center in New York City will be an event that country fans won't want to miss: Legendary performers Dolly Parton, Garth Brooks and Trisha Yearwood have all signed on to be part of the annual ceremony.

The 2016 Christmas in Rockefeller Center tree lighting TV special will celebrate the 84th annual lighting of the world's most famous Christmas tree, which fans will be able to watch live on NBC. Parton, Brooks and Yearwood will be joined by a host of other artists for the special event, including Neil Diamond, Tony Bennett, Tori Kelly, Josh Groban, Sarah McLachlan and, of course, the world-famous Radio City Rockettes.

But the musical stars won't be all that's shining during Christmas in Rockefeller Center; they'll have stiff competition from the Rockefeller Center Christmas tree itself. The 2016 tree is 94 feet tall and will be adorned with over 50,000 multi-colored Christmas lights!

Brooks and Yearwood's appearance on Christmas in Rockefeller Center is especially appropriate this year: The couple will release a holiday duets recordChristmas Together, on Nov. 11. Brooks is currently on the road for his World Tour, with Yearwood along as his special guest, while Parton is touring in support of her recent album, Pure and Simple.

The Christmas in Rockefeller Center TV special is set to air on Nov. 30 at 8PM ET. Parton's new TV movie, Christmas of Many Colors: Circle of Love, will follow.
