Spanger has been out of the show since the Tony Awards on vocal rest, according to a June 22 statement from the producers. Spanger was expected to return June 29.
A new press statement, released June 29, says that Spanger will not return to the cast due to "personal reasons." Her permanent replacement has yet to be determined.

The Rock cast also features "American Idol" finalist and 2009 Tony nominee Constantine Maroulis (The Wedding Singer) as Drew and James Carpinello (Saturday Night Fever, VH1's "So NoTORIous") as Stacee Jaxx.
The onstage band, ARSENAL, comprises music director/keyboardist Henry Aronson, lead guitarist Joel Hoekstra, drummer Jon Weber, bassist Winston Roye and guitar player David Gibbs, who also wrote the original arrangements.
"In 1987 on the Sunset Strip," Rock of Ages production notes state, "a small town girl met a big city rocker and in L.A.'s most famous rock club, they fell in love to the greatest songs of the '80s. . . . [The musical is] an arena-rock love story told through the mind-blowing, face-melting hits of Journey, Bon Jovi, Styx, Reo Speedwagon, Pat Benatar, Foreigner, Twisted Sister, Poison, Asia, Whitesnake and many more."
Rock of Ages was penned by Chris D'Arienzo and features direction by Kristin Hanggi and choreography by Kelly Devine. The creative team also includes scenic designer Beowulf Boritt, costume designer Gregory Gale, lighting designer Jason Lyons, sound designer Peter Hylenski and projection designer Zachary Borovay wither music supervision, arrangements and orchestrations by Ethan Popp.
