The inspirational "Leading the Way" will be sung by the fictional pop group, with Adler accompanying at some performances.

The full amount of any full-price ticket to these performances purchased using the code "ABLABENE" will be donated to Red Cross, directly aiding victims of Hurricane Katrina, according to the producers. The new song will follow the regular performances of the show.

Those interested in the song — and in supporting a good cause Oct. 11-18 — must call (212) 239-6200 or visit Telecharge.com and use code: ABLABENE or go to the box office at Dodger Stages, 340 West 50th Street.

Collections for hurricane relief have been ongoing at the good-works-minded musical in recent weeks.

* Ken Davenport and Robyn Goodman, in association with Walt Grossman, Ruth Hendel, Sharon Karmazin, Matt Murphy and Mark Shacket, present the Off-Broadway musical comedy, winner of the coveted Outer Critics Circle Award for Best Musical Off-Broadway.

The show at Off-Broadway's Dodgers Stages "is a musical-comedy spoof about a fictitious Christian boy-band on the last night of their national 'Raise the Praise' tour. The Boyz — five ultra-talented heartthrobs from Ohio — are lead singer Matthew (the pretty-boy hunk and leader of the pack), Mark (a sensitive young man with a deep faith in Cher), Luke (a bad-boy with an 'interest' in communion wine), Juan (a hot-blooded crooner with a passion for pretty girls) and Abraham (a nice Jewish boy, who's not quite sure how he ended up here...though his mother would sure like to know). The Boyz begin to question their faith in each other, and learn if fate is really holding them together — or if it's just their extra-firm hair gel."

An Equity sitdown of the show is also playing Detroit, at the City Theatre. A Des Moines, Iowa, sitdown premieres in late 2005 at the Temple for the Performing Arts. A national tour is in the works for summer 2006.

The New York cast includes Scott Porter as Matthew; Daniel Torres as Juan; Dennis Moench as Abraham; James Royce Edwards takes on Luke, and Danny Calvert as Mark, the youngest of the Altar Boyz, with Shadoe Stevens as the voice of G.O.D.

Altar Boyz is directed by Stafford Arima and choreographed by Christopher Gattelli. Its music and lyrics are by Gary Adler and Michael Patrick Walker with book by Kevin Del Aguila, based on a concept by Marc Kessler and Ken Davenport. The creative team includes scene design by Anna Louizos, costume design by Gail Brassard, lighting design by Natasha Katz and sound design by Simon Matthews.

Lynne Shankel serves as music director and co-orchestrator with Doug Katsaros. A cast album is in stores.

Performances are Monday, Tuesday, Thursday and Friday at 8 PM, Saturday at 2 PM and 8 PM, and Sunday at 3 PM and 7 PM, at Dodger Stages, Stage 4.

Tickets are $69.99 for all performances ($1 restoration charge included). For more information, visit http://www.altarboyz.com.
