It’s easy to “Always Look on the Bright Side of Life” when the blockbuster Monty Python musical “Spamalot” is in town. The Tony Award winner for Best Musical of 2005 has been mounted in 23 countries around the world. Now the Broadway production returns to bid farewell with a laugh-happy cast that includes two Washington theater veterans.

Arthur Rowan plays — naturally — King Arthur, who goes forth to recruit knights for the Round Table followed by his servant banging two coconuts to make the sound of horses’ hoofs. A graduate of James Madison High School in Vienna and of William and Mary College in Williamsburg, Rowan launched his acting career locally at the Folger Theatre and WSC Avant Bard. An enthusiast of “all things geek,” he was a fan of Monty Python long before being tapped to lead the knights in their quest for the Holy Grail while plagued by killer rabbits and dancing divas.
