It's not easy to live up to an original like Monty Python and the Holy Grail, but Python Eric Idle was the main proponent for adapting the show into the Broadway musical Spamalot. The original had its own relation to music. The original investors included the bands Led Zeppelin, Pink Floyd, and Genesis as well as George Harrison and Andrew Lloyd Weber. All were trying to shelter money from Britain's high tax rates. The film was still produced for just $400,000, and that's why some of the absurdity came more from budget constraints than comic inspiration. The Knights of the Round Table improvised gallops and knocked coconuts together (a radio convention) because they couldn't actually afford horses. The Broadway show cost considerably more to produce. It also changes the story a bit to parody Broadway musical conventions, though it does include a cow catapulted by French soldiers at the Knights of Round Table (scene above).
Spamalot is at the Mahalia Jackson Theater Tuesday through Sunday. Link to videos of the musical after the jump.
