"I will miss this company dearly," Lazar told Playbill.com. His work is preserved on the new two-CD cast album of the musical by Stephen Sondheim and Hugh Wheeler. Lazar's Broadway credits include Les Miserables, A Tale of Two Cities, The Light in the Piazza and more.

Dean, who has played servant Frid since the production's fall 2009 launch, assumes the role of the pompous, misogynistic dragoon Carl-Magnus — lover to the actress Desirée Desiree and husband to Charlotte — starting Aug. 31.

Also on Aug. 29, Sara Jean Ford is exiting the role of Mrs. Anderssen (she's heading over to the Majestic Theatre to play Christine in The Phantom of the Opera). Jessica Grové (Thoroughly Modern Millie, 2008's Sunday in the Park With George) will take Ford's Night Music track as one of the five "liebeslieders."

Starting Aug. 31, Stephen R. Buntrock (Mr. Lindquist since the Broadway run began) will play Frid. Ben Davis (Thoroughly Modern Millie, La Boheme, Les Miz) becomes Mr. Lindquist.

Dean's Broadway credits include Spamalot, Company, The Story of my Life, Man of La Mancha, Jane Eyre, plus Off-Broadway's The Fantasticks and Walmartopia.
