The Broadway staging of Neil Simon's hit marriage-and-divorce comedy, The Dinner Party, will close Sept. 1 after 366 performances and 20 previews at the Music Box Theatre, a spokesman said.

The John Rando-directed comedy began at the Mark Taper Forum in 1999-2000 and moved on to the Kennedy Center in summer 2000 before being plucked for a Broadway run. Emanuel Azenberg is the producer. John Ritter and Henry Winkler, TV stars with box office appeal, helped make the French-set comedy a hit. It opened oct. 19, 2000. Jan Maxwell, Veanne Cox, Len Cariou, Penny Fuller also starred. Larry Miller and Jon Lovitz have since replaced Ritter and Winkler, and Carolyn McCormick stepped into Maxwell's role this summer. Fuller was Tony Award-nominated for playing the hostess of the sadness-tinged play.

The comedy will have its regional debut at Miami's Coconut Grove Playhouse and is likely for Paper Mill Playhouse in the coming season.

Simon will not be away from Broadway for long. His new play, 45 Seconds From Broadway, about a theatre-district diner within a block of the famed street, opens at the Richard Rodgers Theatre this fall.
