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.

'Smash' hasn't even aired yet, but there's already an album in the works. It's been announced that Columbia Records has won the rights to the music from NBC's upcoming midseason musical drama series.

The music will include covers of existing hits plus original songs composed by Marc Shaiman and Scott Wittman, the team behind 'Hairspray' and 'Catch Me If You Can.'

It was also announced that 'Smash' star and former 'American Idol' finalist Katharine McPhee, has signed a solo recording deal with Columbia Records. She previously recorded for RCA and Verve Forecast.

Speaking about the deal, Robert Greenblatt, Chairman NBC Entertainment, said "A musical series should naturally be accompanied by a soundtrack deal, and NBC is very excited to be working with the best. Our Columbia Records partners will guide the soundtrack of 'Smash' into a big component of the show's success. The music will be a driving force ... and we couldn't have asked for better expertise and strategy than this company will provide."
