Just before the final “Bat Out of Hell,” performance, Mr. Dean, who had traded his character’s skinny jeans for his own, returned to his dressing room, mostly emptied, to discuss his rock 'n' roll dreams and post-show despair. These are excerpts from the conversation.

What can you tell me about Falco?

He’s very misunderstood. He doesn’t really do anything too terrible. I mean, he does drug his daughter and he does kill Tink [a teen character in the show], but it’s an accident. We are in a post-apocalyptic landscape, and he’s the only adult around. He is in charge of protecting his family. At his heart, he’s a really good dad. With rage issues.

When the North American tour was canceled, you vented your frustration on Facebook.

I had broken my hand in the show the night that they canceled us. And so I was in pain and in shock. I don’t even remember writing that Facebook post. It got plastered everywhere, and I was like, “Oh no, I called my producers fools.”

How has the New York audience been?

Amazing. The people that this show is right for, they’re my kind of people. I grew up in a little town, Pottsville, Pa., a depressed, impoverished area. Something about the panoramic scope of this music, it was an escape. So I think it’s for people with that story, with that heart that wants to expand and bloom. Romantics, dreamers, common men. I go to the stage door, and I just commune.
