According to a Macy's spokesperson, cast members from Legally Blonde will perform "What You Want," while the Mary Poppins company will offer "Supercalifragilisticexpialidocious." Two other Broadway productions (to be announced shortly) as well as the Radio City Rockettes will also perform.

As previously announced, the parade will kick off with "Making Magic," a new tuned penned by Michael Feinstein with lyrics by Bill Schermerhorn, Macy's creative director. Members of Camp Broadway, the theatre arts education company, will perform the song.

Also of interest to theatre fans: Spring Awakening's Lea Michele and Jonathan Groff will belt out "Give My Regards to Broadway" atop the M&M's Chocolate Candies on Broadway float. That theatre-themed float will feature the M&M's characters taking lead roles in Broadway productions: Green is Elphaba in Wicked, Orange and Yellow star in A Chorus Line, Blue is the Phantom in The Phantom of the Opera, and Red is Spamalot's King Arthur.

The original Christine Daae in London and Broadway's Phantom, Sarah Brightman, will be dressed as a Pirate Queen and will sing "The Journey Home" on the Jolly Polly Pirate Ship; "Hairspray" film star Nikki Blonsky will perform "You Can't Stop the Beat" on the American Classic Malt Shop float; and Feinstein and Tony winner Anika Noni Rose will perform another Feinstein-Schermerhorn song, "Give Me the Key to This Wonderful City," aboard the History Channel's New York Tin Toy float.
