New York's Rockefeller center Christmas tree is all aglow after a star studded concert and lighting ceremony. It's beginning to look a lot like Christmas in midtown Manhattan. NBC broadcast the Rockefeller center Christmas tree lighting ceremony Wednesday night, an event that featured hosts from The Today Show and artists including Catherine mcphee, Alicia Keys, Blake Shelton and Gwen Stefani. The tradition of the tree started with one put up by construction workers building the center in 1931. This year's 82 foot Norway spruce from queensbury, New York, was decorated with 50,000 multi colored LED lights and a crystal star weighing 900 pounds. Audio courtesy and BC. Absent from the ceremony was 68 year old Today Show weatherman Al Roker, who has been battling health issues and reportedly returned to the hospital after missing his first Macy's Thanksgiving Day parade in 27 years.
