"Spamalot" currently stars Tim Curry (search) and David Hyde Pierce (search), who has extended his stay in the musical until April 2006. Simon Russell Beale takes over Dec. 20 for Curry.

"Spamalot," which has a book by Eric Idle (search) and a score by Idle and John Du Prez, begins a North American tour next March in Boston.
