Clay Aiken fans are nothing if not dedicated.

Just check out this report from Buddy TV, which says “Idol: The Musical” is moving to an off-Broadway engagement on Manhattan's 45th street this July. The play, about a group of teens who idolize former contestant Clay Aiken will begin a test run at the 45th Street Theatre on July 5th.

Idol: The Musical is "a satirical musical comedy that focuses on the outrageous and delusional fan base of the hit television show. The musical takes place in Steubenville, Ohio where a group of dork-like students are preparing for their high school graduation after which they are determined to drag themselves out of the dregs of the middle-of-nowhere. There are eight of them; all belonging to the same cult-like club that meets daily in a barn that doubles as a shrine to Clay Aiken.

They are actively ridiculed by the rest of Steubenville; a humiliating situation that doesn't deter their quest for all things Clay. They are victims of A.D.D., Ritalin, their misguided obsessions and their innocent longing for their elusive '15 minutes.'”

If you ever wanted any proof at how unfathomably big American Idol is in our culture, the existence of a musical based on the worship of a former contestant (who really isn't all that famous, really) is enough to gage its magnitude.
