Joy to Beliebers and their grandparents: The original pop star, Tony Bennett, will be showing Justin Bieber how it's done when they both perform at NBC's annual live Christmas tree-lighting ceremony, 'Christmas in Rockefeller Center' later this month.

The roster of big name performers announced by the network spans not only generations, but also genres, with singers Michael Bublé, Cee Lo Green, Faith Hill, Carole King, Katharine McPhee and 'The Voice' winner Javier Colon performing a mix of current hits and holiday classics.

NBC announced that the hour-long special on November 30 will be hosted by the 'Today Show's Al Roker and Savannah Guthrie and will -- natch -- also feature seasonal high-kickers, The Radio City Rockettes. Prior to the primetime telecast, WNBC and other NBC affiliates (check your local listings) will also air an additional live hour of the special.

Despite less-than-perfect weather and a threatened labor strike, last night's 'Christmas in Rockefeller Center' went off without a hitch and featured the 77th annual lighting of New York's iconic Rockefeller Christmas tree, as well as performances by Aretha Franklin, Barry Manilow, Shakira, Michael Buble and the Rockettes, among others.

Co-hosted by Jane Krakowski of '30 Rock' and Zachary Levi of 'Chuck,' the special culminated in the lighting of this year's tree, which stands at a towering 76 feet high and is adorned with more than 25,000 multicolored bulbs. Watch our clip for a sample of the performance by the Rockettes, a peek at Shakira's rendition of 'Santa Baby' and a look at the tree lighting itself.

(8PM, NBC)
Al Roker hosts and Tony Bennett, Harry Connick Jr., Beyonce, the Jonas Brothers, David Cook and Rascal Flatts perform, but the real star of this celebration is the 72-foot-tall Norway spruce that will stand in Rockefeller Center.

Tonight, Roker and the other celebs help flip the switch on the tree's thousands of multicolored lights, an event that officially marks the beginning of the holiday season in New York City.

In fact, this year's tree is such a symbol of the holidays that it's getting its own star: a 550-pound Swarovski crystal ornament that will serve as the tree's topper.
