Put on your dancing shoes. NBC is airing Hairspray Live! as its annual live musical, and it promises to be one of its best yet. The star-studded cast includes Ariana Grande, Jennifer Hudson, Harvey Fierstein, Garrett Clayton, Kristin Chenoweth, Martin Short, Rosie O’Donnell, and newcomer Maddie Baillio as Tracy Turnblad, an unlikely heroine who desegregates a teenage dance show in 1960s Baltimore. As the actors, director Kenny Leon, and producers Craig Zadan and Neil Meron recently told The Advocate, this musical about racial healing has gained newfound relevance in a time when hate crimes against vulnerable communities have spiked. Clearly, America needs musicals — and Tracy Turnblad — more than ever. So tune in Wednesday at 8 p.m. Eastern on NBC, and watch the trailer below.
