There's "The Big Bang" — a 90-minute, two-person musical comedy written by Boyd Graham and Jed Feuer — and then there's "The Big Bang" — a 12-hour, 318-person play written by fictional playwrights Boyd and Jed.

Oregon Cabaret Theatre will present the former, which previews Wednesday and Thursday, March 28-29, at OCT, First and Hargadine streets in Ashland. The musical opens Friday, March 30, and performances are set for 8 p.m. Thursdays through Mondays and 1 p.m. Sundays through May 27.

Graham and Feuer's production ("The Big Bang") is a hysterical romp about two overzealous playwrights, ironically named Boyd and Jed, who hope to — one day — see their play ("The Big Bang") on Broadway.

"The whole premise is that these two guys have written the most extensive musical in the world that tells the history of the world," says OCT director Kymberli Colbourne.

Boyd and Jed's exaggerated play, which covers the history of the world from conception — the big bang— to present day, features 318 cast members, 6,428 costumes, 1,400 wigs and 302 prosthetic devices and will cost $83 million to stage. In hopes of raising the necessary funds, the pair decides to host a "backers' audition" at a posh Manhattan apartment, where they are housesitting.

"The fun of the play is you get to see how they pull this off," Colbourne says.

Short 316 cast members, Jed and Boyd decide to present highlights of the play to investors and endeavor to play all the roles themselves. Roles include Adam and Eve, Columbus and Isabella, Pocahontas and Minnehaha and even Eva Braun, to name a few.

The pair scrounges up items from around the penthouse to use as costumes and props and set out to impress investors with their makeshift production.

"They tiptoe lightly and humourously through a lot of well-known characters, ... (and) we, as the audience, get to enjoy the deliciousness of their successes as well as their failures," Colbourne says.

Local actors and Southern Oregon University graduates Gregg Land and Chris Carwithen play Jed and Boyd, respectively.

Colbourne says Land and Carwithen use every tool in the chest to pull off so many characters.

"It's always fun to see how far a single actor can stretch his talents to cover all these crazy characters," she says.

OCT will use the original score, which includes 16 pop and swing numbers. Musical director Erik Daniells will accompany Jed and Boyd on keyboard onstage as Boyd's brother's boyfriend, Albert.

Jim Giancarlo choreographs, and he's giving the play a PG-13 rating.
