Madison’s Forward Theater Company just wrapped up its extended production of Gutenberg! The Musical!, which was well received by audiences and critics. Reviews of the performances briefly mentioned a local celebrity making a cameo appearance, but Forward kept this aspect of the production a secret and the surprise performers weren’t even named in the playbill.

Forward artistic director Jen Uphoff Gray, who also directed Gutenberg!, says a Broadway production of the play featured celebrity cameos and that was “one of the things I was really charmed by.”

Each night, toward the end of the play, a different guest star, announcing themself as a Broadway producer, emerged from the audience to offer a contract to Doug and Bud, the two main characters in the show.

The role was not complicated, and involved wearing a simple costume and a small microphone. The guest would sing, speak, or, as Gray puts it, “Rex Harrison their way” through a couple of lines.

“Having a different person every night added such a sense of liveness,” Gray says. “The conceit of the play is they don’t know if the play will be picked up,” and the ways each guest star played the part made for a bit of spontaneous uncertainty.

The performers were selected based on being locally famous and having some experience speaking in public, though Gray acknowledges that hitting the stage under the lights and singing a line isn’t the same as delivering a PowerPoint presentation. Some brought a zeal for improvisation.

“[Boys and Girls Club of Dane County president] Michael Johnson, as expected, went into it with his Michael Johnson energy and enthusiasm and, well, he picked Bud up, which was very exciting and unexpected,” Gray says. “And we realized at that point that it really was going to be something different each night.”

Gray was reluctant to name standouts, but did call attention to a couple of pleasant surprises.

“We also learned that the mayor [Satya Rhodes-Conway] has a beautiful singing voice, which was unexpected,” she says. “The UW chancellor [Jennifer Mnookin] had a very nice ad lib: ‘A play about education and literacy? How could I say no?’”
