Directed and choreographed by Denis Jones, performances will continue through June 23.

As previously announced, John O'Hurley will star as King Arthur. He will be joined by Michele Ragusa as The Lady of the Lake, Kevin Cahoon as Historian, John Scherer as Sir Robin, David Hibbard as Patsy, Chris Hoch as Sir Lancelot, Ben Davis as Sir Dennis Galahad and Tally Sessions as Dennis’ Mother/Sir Bedevere. Joining them will be broadcaster Bob Costas as The Voice of God.

“This is a delicious, wonderful comic cast,” said executive producer Mike Isaacson in a statement. “They promise anarchy, mayhem and pandemonium in its highest order. I fear for our audience, I really do, so I encourage all audience members to wear their suits of armor. In fact, anyone showing up in full armor will receive a free lemon freeze!…When I asked Bob Costas to lend his mellifluous tones to our production as The Voice of God, Bob simply replied, ‘When will they stop typecasting me?’”

Based on the 1975 film “Monty Python and the Holy Grail,” Spamalot has a book by Eric Idle and music by John Du Prez. The musical, according to press notes, "tells the legendary tale of King Arthur and his Knights of the Round Table, and raises silliness to an art form." Monty Python’s Spamalot is the winner of three Tony Awards including Best Musical.

The Muny production features scenic design by Sam and Steve Gilliam, sound design by Jason Krueger, lighting design by Seth Jackson and costume design by Leon Dobkowski. Ben Whiteley serves as the musical director, and the production stage manager is Nevin Hedley.
