The musical "lovingly ripped-off" from the film "Monty Python and the Holy Grail," will open Center Theatre Group's 2009-2010 at the Ahmanson Theatre of the Los Angeles Music Center. Performance dates are July 7-Sept. 6. The cast will be headed by John O'Hurley ("Seinfeld," "Dancing with the Stars," Chicago) as King Arthur.

In a statement CTG artistic director Michael Ritchie said, "A little summer madness is a great way to open the Ahmanson's new season. I mean, how can you resist a musical comedy that has catapulting cows, the voice of God and a weaponized herring? I'm glad Los Angeles audiences will finally get to partake in all the fun."

Spamalot joins the previously announced Mary Poppins in the Ahmanson's 2009-2010 season (CTG's 43rd season). The Ahmanson's entire season will be announced in mid-February.

Spamalot features a book and lyrics by Eric Idle, music by John Du Prez and Eric Idle, direction by Mike Nichols, choreography by Casey Nicholaw and is based on the screenplay of "Monty Python and the Holy Grail" by Monty Python creators Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones and Michael Palin.

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).
