The show, directed and choreographed by Jeff Calhoun, had its world premiere engagement at the Denver Civic Theatre on May 7, 2003. The musical received mixed reviews from area critics. The Denver Post's John Moore review stated, "What Brooklyn has today is the cast, creative vision, production values, costumes and staging concept to open there tomorrow. But what it lacks for now is a truly effective story. It needs to seriously address over the next six months how to toughen up a pretty ordinary plot that lacks the power, depth and originality to move and lift its audience as effectively as its music already does."
The cast of that mounting included Eden Espinosa, David Jennings, Ramona Keller, Lee Morgan and Karen Olivo. The majority of these performers are expected to appear in the Broadway production, but only Espinosa has been officially confirmed.
