The engagement in Washington, D.C. will play June 6-July 9. Tickets will be available Feb. 26. For more information, visit www.nationaltheatre.org.

The knights of the Round Table will launch their national tour from Boston's Colonial Theatre (March 7-April 15) before heading to stops at Chicago's Cadillac Palace Theatre (April 19-June 4), Washington, D.C.'s National Theatre (June 6-July 9), Pittsburgh CLO's Benedum Center (Sept. 19-Oct. 1, 2006) and Atlanta's Fox Theatre from (Feb. 20-March 4, 2007). Further stops at major cities in the U.S. and Canada as well as casting are yet to be announced.

The show will also enjoy a new run at the Wynn Las Vegas — currently home to the sole Avenue Q run off Broadway — when the casino resort completes work on a custom-built Spamalot Experience and Grail Theatre in 2007.

Mike Nichols ("The Graduate," "Angels in America") directs the show inspired by the 1975 feature film comedy "Monty Python and the Holy Grail" which landed at Broadway's Shubert Theatre for a St. Valentine's Day (Feb. 14) start and a St. Patrick's Day (March 17) opening.

The self-proclaimed "lovingly ripped-off" show features a book by Idle based on the screenplay he co-wrote with Monty Python creators Graham Chapman, John Cleese, Terry Gilliam, Terry Jones and Michael Palin. The new score with music and lyrics by Idle and composer John Du Prez ("A Fish Called Wanda") also includes songs ("Brave Sir Robin" and "Knights of the Round Table") from the original film as well as Python signature "Always Look on the Bright Side of Life." Spamalot tells the tale of King Arthur and his Knights of the Round Table on their quest from God (voiced by a familiar actor) for the Holy Grail — with a short stop in the dazzling Spam-filled land of Camelot. The show boasts "a chorus line of dancing divas and knights, flatulent Frenchmen, killer rabbits and one legless knight" who sing and dance. (Python devotees will be happy to know The Knights Who Say "Ni!" also make an appearance.)

The musical earned 14 nominations for the 2005 Tony Awards, winning prizes for Best Musical, Best Direction (Mike Nichols) and Featured Actress (Sara Ramirez).

Todd Ellison is musical director and vocal arranger. Larry Hochman provides orchestrations, Glen Kelly handles music arrangements and Michael Keller is musical coordinator.

The design team for Spamalot features Tim Hatley (set, costume), Hugh Vanstone (lighting), Gregory Meeh (special effects) and ACME Sound Partners (sound).
