"I still can’t believe this happened," Hurder captioned the social media post. "More thoughts and feelings and full blown diary entries to come….but for now…. I got to sing to sing her song with her on her line. On her stage. I got to dance the dance next the legend that is [Charlotte D'Amboise]. This moment is burned into my soul forever. My GOD am I grateful."

It ran for 15 years and was the longest-running Broadway show when it closed on April 28, 1990, playing 6,137 performances—and has continued to span the globe for decades.
