If the mom-to-be knows the entire score from Hairspray, Rent, or Phantom of the Opera, she’ll sing the praises of the Broadway Baby Shower. For lovers of the dramatic arts, what could be more fun? The beauty of planning a Broadway Baby Shower is its versatility. Revive an old classic musical like Pajama Game or Carousel and build your theme around the title, tone, or time frame. Use a show title with a twist — Avenue Poo (Avenue Q), Greased (Grease), or The Producers (perfect as is).
