BROADWAY was awash in red ink yesterday as five shows posted closing notices in the wake of Sunday night’s Tony award telecast.

The combined losses totaled about $14 million.

Leading the pack of flops was Frank Wildhorn’s ”The Civil War,” which went home empty-handed on Tony night. The show will shutter Sunday at a loss of almost $8 million.

Despite Tony wins for cast members Kristin Chenoweth and Roger Bart, ”You’re a Good Man, Charlie Brown” also will go dark Sunday, losing $4.5 million.

On the straight-play front, ”The Lonesome West,” Martin McDonagh’s follow-up to his hit ”The Beauty Queen of Leenane,” will close this weekend at a loss of over $1 million.

”Not About Nightingales,” the prison play penned by a young Tennessee Williams, will pack up Sunday – two weeks shy of its announced June 27 closing date. Although the stark and brutal drama received glowing reviews, it never caught on with audiences. It recouped only a portion of its near $2 million investment.

The thriller ”Night Must Fall” will close June 27, when its star, Matthew Broderick, departs. Production sources said the play, produced by the non-profit National Actors Theater, made a small profit.

”The Sound of Music,” a hold-over from last season, will also close at the end of the month.

Two plays showing surprising strength are ”The Weir,” which wasn’t even nominated for a Tony, and ”Closer,” which lost out to ”Side Man.” Both shows make a profit each week, and ”Closer” is expected to return its $1.4 million investment this month.
