It's time to transport back to Baltimore in the 1960s for Hairspray Live!

The debut promo for NBC's next live musical spectacular aired Friday during the network's Olympics broadcast and we got our first look at the special's all-star cast in full costume. Newcomer Maddie Baillo had her Tracy Turnblad updo sprayed to tower perfection.

The rest of the cast includes Harvey Fierstein as Edna Turnblad, Jennifer Hudson as Motormouth Maybelle, Ariana Grande as Penny, Kristin Chenoweth as Velma Von Tussle, Martin Short as Wilbur Turnblad, Derek Hough as Corny Collins, Dove Cameron as Amber and Garrett Clayton as Link Larkin.

Hairspray Live! airs Dec. 7 at 9/8c on NBC.
