Warning: Some language and/or graphic staging may offend or excite." That's just the sort of disclaimer to help sell the world premiere musical, Outrageous, about the friendship between a schizophrenic and an aspiring drag queen, slated for Sept. 19-Oct. 21 at The Canadian Stage Company's Berkeley Street Theatre in Toronto.

The disclaimer for the CanStage musical by Brad Fraser (book and lyrics) and Joey Miller (music and additional lyrics) just might be working: Five additional preview performances have been added, Sept. 19-23, making the preview period run Sept. 19-27, with an opening set for Sept. 28.

Fraser, who previously penned the provocative Unidentified Human Remains and the True Nature of Love, directs the tuner, based loosely on the 1977 cult movie of the same name.

The focus of the show is on Liza, a schizophrenic played by Lorretta Bailey (Les Miserables, CanStage's Into the Woods), and Robin, a hairdresser and aspiring female impersonator, played by Thom Allison (Rent, Miss Saigon, The Who's Tommy).

The show about social outcasts is billed as "raucous, raunchy, sad and sweet." The 1977 picture was written and directed by Richard Benner and based on stories "Making It" and "Notes on Making It" in a book by Margaret Gibson titled "The Butterfly Ward."

The Outrageous company also includes Tamara Bernier, Susan Henley, Karen Leblanc, Sharron Matthews, Tim Murphy, Ed Sahely, Timothy Sell and Timothy Howar.

Sergio Trujillo, of Fosse, choreographs. Diane Leah is musical director. Designers are David Boechler (set and costumes), Bonnie Beecher (lighting), Henry Monteforte (sound).

Composer-lyricist Joey Miller is the Dora Award-winning writer of That Scatterbrained Booky.

Outrageous tickets are $20-$40. CanStage's Berkeley Street Theatre is at 26 Berkeley St. Call (416) 368-3110 for information, or try the web site at www.canstage.com.
