Fundraisers and free beats are popping up on the South Fork this weekend:
BEACH BENEFIT Retired Navy SEALs and reps for the nonprofit Navy SEAL Foundation will be on hand Saturday for the second annual "Honoring Our Warriors, Supporting Their Families" benefit at Navy Beach in Montauk (16 Navy Rd.). From 4 to 6 p.m., guests at the cocktail party can mix with the armed forces members and enjoy live music from Hamptons performer Nancy Atlas. The RSVP date has passed, but a $40 donation at the door gets you in (631-668-6868).
STRETCH SPINS Not only has DJ and producer Stretch Armstrong spun deep hip-hop, reggae and other underground beats in Manhattan for more than two decades, but he's helped some of rap music's biggest artists get their big break via his work in radio -- so obviously he's got some skills. Catch him -- for free -- as he contributes some mixing live to the "Summer Set Saturdays" party place noon-7 p.m. Saturday at the Montauk Beach House (55 S. Elmwood Ave.) RSVP at firstname.lastname@example.org, details at thembh.com.
LONGEST DAY Although it was officially May 26, native Long Islander and reality TV star Scott Disick will celebrate his birthday Saturday at 1 OAK in Southampton. Given that he's the longtime boyfriend of Kourtney Kardashian, who is summering in the Hamptons while filming the next installment of her reality show, bank on a crowd of folks RSVPing for table service (via email@example.com, 631-204-5433).
Meanwhile, iconic fashion designer Calvin Klein is only one of the boldfaced names slated to take part in Saturday night's 14th Annual Midsummer Night Drinks, 6-9 p.m. in Southampton in support of the nonprofit God's Love We Deliver -- tickets start at $350 (glwd.org).
Also, the Ellen Hermanson Foundation's annual Summer Solstice gala runs 7-9 p.m. at the home of newsman Chuck Scarborough, with tickets beginning at $300 (includes an after-party at Redstix in Water Mill). Tickets available via shop.ellensrun.org.
