Take heart, all you Python addicts: the Tribune reports that "Spamalot," a musical based on the classic comedy Monty Python and the Holy Grail, will be playing in Chicago at the end of the year. With words and music by Eric Idle, and directed by Mike Nichols (!), the musical will have a pre-Broadway run here in Chicago in December and next January. Spamalot will also have all-new songs and words, so you will not be able to recite the text of the movie along with the actors, alas.
