Aiken will be making his Broadway debut in the role originated on Broadway by David Hyde Pierce. His stint begins Jan. 18, 2008, and is scheduled to continue through May 4.
"Clay Aiken is amazing beyond that glorious voice. Turns out he is an excellent comic actor and a master of character," said director Mike Nichols in a release. "People will be surprised by his wide ranging talent, since the first impression is of great country charm and a singer to remember. This guy is not only a star, he is a lot more. We are lucky to get him for Spamalot."
Aiken — who was bested by Ruben Studdard during the second season of "American Idol" — has gone on to sell more than 6 million albums, co-author a best selling book ("Learning to Sing: Hearing the Music in Your Life") and play six sold-out concert tours. He was a focus of the short-lived Off-Broadway musical Idol: The Musical and has appeared on "Ed," "Saturday Night Live" and "Scrubs."
Monty Python's Spamalot, which celebrated its 1,000th performance Aug. 9, opened at Broadway's Shubert Theatre on March 17, 2005, following previews from Feb. 14.
Mike Nichols ("The Graduate," "Angels in America") directed and Casey Nicholaw ( The Drowsy Chaperone) choreographed the show that was inspired by the 1975 feature film comedy "Monty Python and the Holy Grail." The musical tells the tale of King Arthur and his Knights of the Round Table on their quest from God for the Holy Grail - with a short stop in the dazzling Spam-filled land of Camelot.
Spamalot earned the 2005 Tony Award for Best Musical and took home honors for direction (Mike Nichols) and one of its stars (Sara Ramirez). The musical still plays on Broadway at the Shubert Theatre and currently enjoys runs in London, Las Vegas and a national tour. An Australian production is slated to play Melbourne in November.
