Who remembers the South Park episode where Cartman founded a boy band and called it Fingerbang? Well, somewhat in that same spirit comes the musical comedy that lampoons boy bands and the culture of Christian-themed music all at the same time. (Come to think of it, Cartman assaulted Christian music, too.) Street Theatre Company once again makes an interesting choice with this piece, which ran Off-Broadway for nearly five years, plus enjoyed some touring action both domestically and abroad. The show’s fictitious vocal group comprises Matthew, Mark, Luke … and Juan … and Abraham. Their concert dates feature tight harmonies and kick-ass choreography, not to mention a message of unity via numbers like “Church Rulez,” “The Miracle Song,” “Everybody Fits” and “La Vida Eternal.” Also, keep an eye out for the delightfully twisted “Something About You,” a perfectly stylized keyboard ballad extolling abstinence and including the line, “Girl, you make me want to wait.” The terminally “sensitive,” coyly derivative score is by Gary Adler and Michael Patrick Walker, the book by Kevin Del Aguila, and what makes the whole thing work is the way the material never fails to takes itself seriously (or try, at least). Bakari King directs and choreographs, and among the heartthrobbish performers in his cast are Michael Holder and Alan Smith plus Humberto Figueroa, Taylor Casey and Patrick James.
