R&B singer Beyonce Knowles, Elton John and Carrie Underwood will headline “Movies Rock,” a two-hour music-and-film event, put on by Conde Nast Media Group, at the Kodak Theater on Dec. 2. The show will air Dec. 7 on CBS. Beyonce will sing “Over the Rainbow,” Underwood will perform “The Sound of Music,” Fergie and Jennifer Hudson will pay tribute to Bond films with “Live and Let Die” and “Goldfinger,” and John Legend and Mary J. Blige will sing “As Time Goes By.” Elton John, who won an Oscar for “Can You Feel the Love Tonight” from “The Lion King,” will honor music from animated movies, and John Williams will perform a medley from his original scores, which include “Jurassic Park” and “Raiders of the Lost Ark.” “We wanted to create an extraordinary show that would pay tribute to the indelible impact music has on film,” said Richard Beckman, president of Conde Nast Media Group. “Movies Rock” will be supplemented by a magazine component, also called Movies Rock, which will be packaged with 14 December Conde Nast titles. Publication will highlight stars, directors and musicians, and Bill Murray is the cover. Vanity Fair’s Graydon Carter will serve as editorial director of the special issue, and Mitch Glazer will serve as editor.
