Lovingly ripped from the film classic Monty Python and the Holy Grail, Spamalot has everything that makes a great knight at the theatre, from flying cows to killer rabbits, British royalty to French taunters, dancing girls, rubbery shrubbery, and of course, the lady of the lake. Spamalot, which first galloped onto Broadway in 2005, features a book & lyrics by Eric Idle and music by John Du Prez and Eric Idle.
