Monty Python's Spamalot is a musical comedy lovingly ripped off from the 1975 film Monty Python and the Holy Grail. Like the film, it is a highly irreverent parody of the Arthurian Legend, but it differs from the film in many ways, especially in its parodies of Broadway theatre. Eric Idle, a member of the Monty Python team, wrote the musical's book and lyrics and collaborated with John Du Prez on most of the music.
