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.
