Fall forward

Was this summer weird or what? Now that it — and, hopefully, the rain and constant celebrity deaths — is behind us, we’re excited for fall. What’s there to look forward to after Labor Day? Pretty much everything. But here’s a start.

1. Barbra Streisand at The Village Vanguard

Sept. 26;

barbrastreisand.com

The diva of all divas re-emerges from retirement yet again to sing at the downtown club where the Brooklyn native opened for Miles Davis in 1961. Babs will belt jazz standards from her latest CD, “Love Is the Answer,” for 100 of the luckiest people. If you’re not one of the luckiest peeps, no doubt there

will eventually be a live CD and DVD. Enter ticket sweepstakes on the site by 5 p.m. tomorrow.

2. Rock and Roll Hall of Fame 25th Anniversary

Madison Square

Garden, Oct. 29, 30; rockhall25.com

It’s a battle of the bands, but everyone has already won. Bruce Springsteen & the E Street Band, Simon & Garfunkel, Crosby, Stills, Nash & Friends and Stevie Wonder perform the first night;

Eric Clapton, Aretha Franklin, Metallica and U2, the second. Also coming for HOF25: a nine-DVD box set

of induction ceremony appearances and performances and a celebratory book.

3. Seinfeld Reunion

On Larry David’s “Curb Your Enthusiasm” over several episodes. Season starts

Sept. 20.

Working together for the first time in 11 years, everyone’s favorite neurotic quartet — Jerry Seinfeld, Jason Alexander, Julia Louis-Dreyfus and Michael Richards — bring their dysfunctional hijinks to “Seinfeld” co-creator’s

biting comedy, under the pretense that NBC is pushing David to do a reunion.

4. Manhattan Cocktail

Classic

Astor Center, Oct. 3, 4; manhattancocktail-

classic.com

New York’s first ever weekend party, uh, festival, dedicated to the cocktail — not just sipping one, but the history and craft thereof. Highlights include seminars from Milk & Honey’s Sasha Petraske (on hosting a cocktail party) and connoisseur Dave Wondrichn, plus field trips to bars. Other wine geeks, mixologists and storied bar owners will rally festgoers with drinks and tales. Tickets go on sale today.

5. The New York Philharmonic with Alec Baldwin and Alan Gilbert

Sept. 16; nyphil.org

The “30 Rock” star will preside over the opening night gala, “Live from Lincoln Center” on Sept. 16, and host the season’s weekly radio broadcasts. Doubly thrilling is the official debut of Gilbert as musical director — the first native New Yorker to helm the orchestra.

6. Ana Sui for Target

In stores Sunday to Oct. 17; target.com

It’s cheap, chic, so New York — and the line is inspired by the designer-conscious “Gossip Girl,” which returns Sept. 14! Update your wardrobe with a $50 budget. XOXO

7. “Superior Donuts”

Opens Oct. 1 at the Music Box Theatre; tickets, 212-239-6200; superior-donuts.com

Playwright Tracy Letts is

on a roll after “Killer Joe,” “Bug” and the Pulitzer Prize winner, “August: Osage County” — all excellent

and all very different from each other. He switches tone again for his new

one, which is more of a

comedy. Plus: Michael McKean a k a David St. Hubbins is in it! In previews starting Sept. 16.

8. “Glee”

Series starts Wednesday, 9 p.m., on Fox; fox.com/glee

A different type of high school musical: In this hilarious dramedy, it’s the McKinley High Glee Club — and their hopeful coach — versus the cheerleaders and the football team. The pilot’s glee-club version of “Don’t Stop Believing” put the Journey power ballad back at the top on iTunes. From the creator of “Nip/Tuck.”

9. Monty Python reunion Ziegfeld Theater, Oct. 15

Always looking on the bright side of life, even in death. Apparently, Graham Chapman, who died in 1989, will join John Cleese, Terry Gilliam, Eric Idle, Terry Jones and Michael Palin to celebrate the 40th anniversary of the pioneering comedy troupe — and promote the new documentary “Monty Python: Almost the Truth (The Lawyer’s Cut).” To go with that, IFC will air a “Pythonathon” from Oct. 18-24.

10. “A Serious Man”

Opens Oct. 2 at theaters throughout the city

The latest Coen brothers flick features a college prof trying to find clarity. That’s for the grown-ups. For tweens and rabid Robert Pattinson fans alike, the Twilight vampire saga continues with “New Moon.”

11. James Ellroy’s “Blood’s a Rover” In bookstores Sept. 22

A sound of alarm to book clubs all over: The master of darkness is back with his first noir-vel in eight years, concluding his Underworld U.S.A. trilogy.

12. End of Season for the Mets

Oct. 4

Fans and team doctors have suffered enough. Next!
