The Big Bang, the Off-Broadway musical spoof of the people who make musicals -- and their desperate plea for backers -- will have its final performance April 16 at the Douglas Fairbanks Theatre.

Audiences at the National Alliance for Musical Theater conference in fall 1999 went wild for an excerpt of the two person The Big Bang, about a couple of musical comedy writers trying to raise dough for a show about the history of the world, from creation to the year 2000.

Set in a borrowed Park Avenue apartment, The Big Bang only requires two people, one set and one pianist and piano, and producers attending the annual NAMT conference -- which includes a showcase of new works -- nudged each other and saw how inexpensive it was to produce. It seemed prime for a New York staging, and for a New York audience.

Producers Eric Krebs and Nancy Nagel Gibbs put it into the Fairbanks. The comic musical, performed by its authors, composer Jed Feuer and lyricist librettist Boyd Graham, opened March 1 after previews that began Feb. 15.

It is thought the show will have a regional and stock future due to its affordable cast size and goofy, affable, theatre-hip quality. *

Feuer and Graham play themselves, in effect, desperately pitching a show to potential investors. The pair, in real life, penned the 1992 Off Broadway musical, Eating Raoul, which has seen stagings around the world, from Munich to Los Angeles.

Graham directs The Big Bang, which offers such song titles as "Free Food and Frontal Nudity" (a song for Adam and Eve), "Pyramid," "Wake Up, Caesar," "A New World" (for Columbus and Queen Isabella), "We're Gonna Fly" (for the Wright brothers) and more. The show within the show follows, roughly, the history of Western civilization.

Designers are Edward T. Gianfrancesco (set), Basil De Maurier (costumes), James Vermeulen (lighting) and Ray Schilke (sound).

Standbys for the authors are Kevin Del Aguila (Boyd) and David Benoit (Jed). Albert Ahronheim is the musical director.

Producer Krebs runs Off-Broadway's Douglas Fairbanks and John Houseman theaters. Among his many producing credits are Electra, It Ain't Nothin' But the Blues, bash and This is Our Youth.

The Big Bang tickets are $30-$45. The Douglas Fairbanks is at 432 W. 42nd St. Call (212) 239-6200 for information.
