There are weddings. There are celebrity weddings. And then there is the time Sly Stone decided to marry his actress fiancée, Kathy Silva, at Madison Square Garden before an audience of 23,000.

For the musician who turned rock concerts into joyous, genre-defying spectacles, a church was never going to suffice—neither was a tuxedo. In George W. S. Trow’s deliciously detailed New Yorker account of the wedding’s creation, Stone gives friend, producer, and Columbia Records executive Stephen Paley his marching orders in a single sentence: “I wish you would make my wedding the biggest event this year.”

Within weeks, New York’s creative elite had answered that call. Halston was sketching glittering gold looks. Joe Eula was storyboarding a theatrical procession. Richard Avedon (on assignment from Vogue) was preparing his camera. It was announced as part of a Sly and the Family Stone concert, conceived from the outset as equal parts matrimony, fashion spectacle, and rock show.

Stone and Silva had already done things in their own order. By the spring of 1974, the couple had welcomed a son, Sylvester Jr., and after calling off an earlier ceremony in Hawaii, decided it was finally time to make things official. Speaking to Vogue about their wedding plans, Stone’s explanation was characteristically offhand: “I have a little boy now...and I don’t want him to be a liar when he says ‘dada.’” Silva, naturally, had the more romantic take: “When you are as much in love as Sly and I are, you just go to extremes and get married.”

As outlandish as the idea was, there was a certain logic to it. By 1974, Stone was one of the biggest stars in America. Sly and the Family Stone had rewritten popular music with “Dance to the Music,” “Family Affair,” and “If You Want Me to Stay.” Their electrifying dawn performance at Woodstock had become the stuff of rock legend, while Stone himself was as recognizable for his flamboyant style (he dabbled in rhinestone-studded Nudie suits, Larry LeGaspi, towering platform boots, and extravagant hats) as his boundary-pushing sound. So when a June 5 date at Madison Square Garden was already booked, Stone decided the night could also double as his wedding. “I could do a gig, get paid, and get married at the same time,” he explained in his memoir.

Besides, the Garden had long proved itself more than a sports arena. Boxing matches gave way to political conventions, the circus rolled in every winter, and just 12 years earlier, Marilyn Monroe had stepped onto its stage to serenade President John F. Kennedy with her breathy rendition of “Happy Birthday.” It was a place built for spectacle. Stone merely added wedding vows to its repertoire.

If anyone could turn Madison Square Garden into a cathedral, it was Joe Eula. The illustrator, fashion polymath, and creative impresario had already helped orchestrate the legendary Battle of Versailles fashion show and now approached Stone’s wedding with the same theatrical ambition. “You’ve got to keep something happening every minute,” he declared (per the New Yorker) as he mapped out the evening's procession.

His original vision was even grander than what audiences ultimately saw. White doves were meant to soar through the arena before the ASPCA intervened. Donyale Luna was supposed to fly overhead “like Tinker Bell,” scattering gold glitter over the crowd, until officials demanded a $125,000 security bond. Security concerns also nixed Stone and Silva’s planned walk through the arena. Yet Eula’s flair remained intact. Imagining the procession that would eventually open the ceremony, he enthused, “Those 12 black models are going to look like Botticelli in 3-D. Imagine black girls in black Halston dresses carrying gilded palms. Arise, Cleopatra, Queen of the East River!”

And the bride wore Halston. So too did the groom, the wedding party, and even the procession. Looking back in his 2023 memoir, Thank You (Falettinme Be Mice Elf Agin), Stone recalled the fitting with delight. “You know, darling, you’ll look fabulous,” Halston promised.

Gold became the evening's unifying motif. Stone strode onto the Garden stage in a shimmering gold jumpsuit, its zipper left provocatively open to mid-chest beneath a sweeping floor-length cape fastened at the neck and cinched with a sculptural gilt buckle—all cut from Halston’s custom “3-D sequined” chiffon. Silva matched him in the very same fabric, her halter gown draped in liquid folds that pooled dramatically behind her, while crystals scattered through her waist-length hair caught the arena lights with every turn. Elsa Peretti jewelry—a sculptural cuff, delicate bracelets, and rings—provided the only punctuation.

Ahead of them, 12 statuesque Black models glided across the stage in a procession of black Halston jersey gowns—no two alike. Some were Grecian and one-shouldered, others long, fluid columns, each accessorized with gleaming sculptural cuffs and armlets that caught the light against the matte black fabric. It was less a bridal party than a fashion tableau. When Richard Avedon photographed the newlyweds, Vogue writer Leo Lerman captured the effect in six unforgettable words: “flabbergastingly Halstoned in golden 3-D sequins.” (Halston was reportedly paid $10,000 for at least 30 looks).

Following Eddie Kendricks’s opening set and a brief intermission, the lights came up on what the New York Times aptly described as “a production number all the way.” The procession of Black models emerged first, followed by the wedding party, as Stone and Silva took their places behind matching microphone stands, facing not only nearly 23,000 concertgoers but also a phalanx of television cameras and photographers gathered just below the stage. Stone never removed his signature aviator sunglasses. As Sly and the Family Stone eased into the opening strains of “Family Affair,” fans surged into the aisles and climbed onto their seats, prompting Stone’s mother, K.C. Stewart, to step to the microphone with a gentle but necessary reminder: “This is a sacred ceremony.” His niece Lisa then sang a spiritual before Bishop B. R. Stewart began the service.

For all its theatrical flourishes, the ceremony itself was remarkably traditional. Stewart officiated as Stone and Silva exchanged wide, filigreed wedding bands that Stephen Paley—who had one final duty that evening as best man—had procured from Lamston’s five-and-ten for the price of 59-cents each. Stone grinned through the vows from behind his dark lenses before Bishop Stewart pronounced the couple husband and wife to the roar of nearly 23,000 witnesses.

The celebration continued uptown at the Waldorf-Astoria’s storied Starlight Roof, where Columbia Records reportedly spent $25,000 on a reception for some 400 guests. Gold-engraved invitations instructed invitees to “Wear something gold,” while behind the scenes, the planning bordered on military. There were discussions about armed security, insurance policies, and guarded stairwells; Eula sparred over florists, and Paley even tried—unsuccessfully—to convince the hotel to reopen the Starlight Roof to the night sky.

Inside, every detail carried its own symbolism. As Stone later explained in his memoir, the Japanese cuisine and soul-food buffet honored “the Hawaiian bride and black groom.” New York State champagne saluted the city that had hosted the spectacle (though it might have had something to do with the budget), while the towering round wedding cake, crowned with a gleaming gold record, paid tribute to “the business I was in.”

The guest list read like a who’s who of 1970s glamour. Andy Warhol, Halston, Diane von Furstenberg, Penelope Tree, Donyale Luna, Lance Loud, Baby Jane Holzer, Lorna Luft, Jamie Bernstein, Wendy Stark, and photographer Francesco Scavullo drifted through the Starlight Roof in varying interpretations of the evening’s golden dress code.

Photographs from the reception capture a sartorial free-for-all: denim cutoffs rubbed shoulders with sweeping maxi gowns, sequins mingled with jersey, and enough gold jewelry to rival the newlyweds themselves. Halston, ever the picture of restraint, arrived in his signature black turtleneck beneath a tailored jacket. Warhol looked more English don than pop-art provocateur in a brown blazer, striped tie, and button-down shirt. Von Furstenberg, meanwhile, interpreted the brief with characteristic ease, pairing a jade-green wrap ensemble with a cascade of gold necklaces.

Andy Warhol’s review, as reported by Newsweek, was perfectly Warholian: “A fun party.” Stone’s own summary of the party was vaguely recounted in his memoir. “The party was drinking and dancing and smoking and joking,” he wrote years later, “the kind of thing you remember only from the pictures you see afterward.”

Alas, like so many rock-and-roll romances of the era, Stone and Silva’s marriage proved far less enduring than the spectacle that inaugurated it. They separated mere months after their union and divorced just two years later. Yet the wedding distilled everything irresistible about 1970s glamour into a single evening: Halston, Warhol, Avedon, sequins, celebrity, and just enough excess to make it unforgettable. Their marriage may not have lasted, but their gilded wedding has never lost its luster.
