NEW YORK - He's a little bit rock 'n' roll, she's a little bit country. Together, they're going to be a whole lot of Broadway.

Donny and Marie Osmond will be appearing in a Christmas show at the Marriott Marquis Theatre starting Dec. 9. The 12-performance run ends Dec. 19.

The show, titled "Donny & Marie -- A Broadway Christmas," marks the first time the siblings have shared a Broadway stage. They'll be singing favourite hits and holiday songs with a live band.

Donny starred in "Joseph and the Amazing Technicolor Dreamcoat" in Toronto for six years and made it to Broadway as Gaston in "Beauty & The Beast." Marie made her Broadway debut in 1997 as Anna in "The King and I" and toured as Maria in "The Sound of Music."
