The Chicago regional premiere of Spamalot, the side-splitting musical comedy "lovingly ripped off" from the 1975 film Monty Python and the Holy Grail, will preview December 31, open January 6, and run through March 13, 2011. With a book and lyrics by Eric Idle and an entirely new score created by Idle and John Du Prez, Spamalot will be directed by Drury Lane Oakbrook's Artistic Director William Osetek. Osetek has directed numerous productions at Drury Lane Oakbrook including the annual holiday favorite, A Christmas Carol. The multi-Tony Award winning Spamalot debuted on Broadway in 2005 and recently made its final appearance after 1,574 hysterical performances. Telling the legendary tale of King Arthur and the Knights of the Round Table and their quest for the Holy Grail, Spamalot features a chorus line of dancing divas and knights, flatulent Frenchmen, killer rabbits and one legless knight.
