A stage play, written by the late Monty Python star Graham Chapman while he was working on the movie Monty Python and the Holy Grail was performed for the first time in Atlanta Friday night, 11 years after Chapman's death.

The comedy, O Happy Day!, about a bride who's pregnant with a child that's not the groom's, debuted in a comedy club, Dad's Garage Theatre.

Chapman's archivist Jim Yoakum was quoted on Chapman's official Web site as saying that he was stunned when he was first shown the script. "Here was this incredibly funny script, written by a genius of modern comedy. Not only was it totally unknown -- it was a play! Not a medium normally associated with Graham. It's like discovering a Christmas pantomime written by Oscar Wilde."
