The musical about a fictional Christian boys band will begin a 30-week national tour on Oct. 10 with a three-week engagement at the LaSalle Theatre in Chicago.

A complete tour schedule will be announced soon.

Meanwhile, in New York, the original production will welcome back one of its founding cast members. Ryan Duncan, who created the part of Juan (as in Matthew, Mark, Luke and Juan) will rejoin the show on May 1. He replaces Clyde Alves, who leaves April 30.

Jason Celaya became the musical's new Matthew on April 3. He is making his New York debut in Altar Boyz. Regional credits include Annie Get Your Gun, West Side Story, Fiddler on the Roof, and Joseph and the Technicolor Dreamcoat.

Tyler Maynard, Andrew C. Call and Dennis Moench are also currently in the New York cast. Altar Boyz opened March 1, 2005. The 90-minute entertainment is directed by Stafford Arima and choreographed by Christopher Gattelli. Altar Boyz has music and lyrics by Gary Adler and Michael Patrick Walker with book by Kevin Del Aguila, based on a concept by Marc Kessler and Ken Davenport.
