As previously announced, several Broadway musicals and stars will be featured during the annual Macy's Thanksgiving Day Parade, which will be broadcast live on NBC-TV Nov. 27 beginning at 9 AM ET. According to a Macy's spokesperson, the annual parade will boast performances from the casts of Irving Berlin's White Christmas (performing a medley of "I've Got My Love to Keep Me Warm" and "White Christmas"), In the Heights (performing the title song), South Pacific (singing "There Is Nothing Like a Dame") and The Little Mermaid (performing "Under the Sea").

Also of interest to theatre fans: The cast of the forthcoming revival of Hair will belt out "Aquarius" atop the New York Tin Toy float; Tony winner Kristin Chenoweth will sing "The Christmas Waltz" on The Care Bears Winter Fun-derland float; and Tony winner Idina Menzel will offer "I Stand" on the M&M's on Broadway float.

The parade will conclude with members of Camp Broadway — joined by Kermit the Frog — performing "I Believe in Santa Claus." A group of 300 kids, ages 10-17, will sing the tune, which was penned by Wesley Whatley and Bill Schermerhorn, Macy's creative director.
