The Rockettes held an open rehearsal on Thursday, October 11, to preview the brand-new finale to the 2018 Radio City Christmas Spectacular. The new finale, “Christmas Lights,” will begin following the iconic “Living Nativity” scene. As the North Star appears, aerialists will fly across the stage as 100 drones form various shapes and patterns surrounding Santa Claus. The Rockettes will then be revealed as they perform new choreography in new costumes.
