The set-up for Jim Barne and Kit Buchan’s new comedy, which is also a musical, is as old as the hills: two people traveling to the same wedding are thrust together by fate. Dougal, a naive Brit, flies to New York for his father’s second wedding. Robin, the bride’s sister, has to pick Dougal up from the airport. By popular demand, the show’s run has been extended. Sam Tutty and Dujonna Gift star. —Jensen Davis
