The group's abstinence-friendly hit? "Girl, You Make Me Wanna Wait."

NYMF is presenting a number of new musicals in full productions Sept. 13-Oct. 3 in midtown Manhattan (The Altar Boyz plays Sept. 16-Oct. 3). The goal of NYMF is to present a forum for dawning works as a link between readings and full commercial or regional lives. NYMF invites production-ready shows and producers into its schedule; NYMF doesn't produce the shows.

Ken Davenport (The Awesome 80s Prom) and Robyn Goodman (Avenue Q) are producers of The Altar Boyz.

The show, in which "N'Sync meets Nunsense," plays six performances at The 47th St. Theater – The Puerto Rican Traveling Theatre, 304 W. 47th Street. Tickets ($15) go on sale Aug. 19.

The Altar Boyz is "about a struggling Christian boy-band riding the wave of America's latest fascination with religion," according to the announcement. "Armed with catchy melodies, freaky moves and product in their hair, the self-anointed apostles of pop (Matthew, Mark, Luke and Juan) bring their soul-saving tour to New York City, with their heavenly hits like 'Girl, You Make Me Wanna Wait.'" The show is conceived by Marc Kessler (The Manhattan Rhythm Kings) and Ken Davenport. Its creative team includes Gary Adler and Michael Patrick Walker (songs), Kevin Del Aguila (book), Stafford Arima (director), Christopher Gattelli (choreographer) and Anna Louizos (scenic design).

The cast will include Cheyenne Jackson (Aida) and David Josefsberg (The Joys of Sex). Additional casting will be announced.

Director Arima is a 2004 Olivier Award nominee for staging Ragtime. His current work in New York is Off-Broadway's Children's Letters To God.

In the scattered NYMF schedule, The Altar Boyz performs Sept. 16 (8 PM), Sept. 19 (4:30 & 8 PM), Sept. 29 (1 PM), Oct. 1 (4:30 PM) and Oct. 3 (4:30 PM).

The full slate of shows being presented in the New York Musical Theatre Festival has not been announced yet.
