Nearly every musician slated to take the stage at the “Great American State Fair,” billed by President Donald Trump as a birthday bash for America, have backed out of performing.

Organizers of the event, a 16-day bonanza in D.C. to celebrate the nation’s 250th anniversary, announced their lineup on Wednesday, with artists including Young MC, the Commodores and Martina McBride. As of Friday, though, only a few of the nine scheduled acts remain on the roster, including Flo Rida, Vanilla Ice and Fab Morvan, half of 1980s pop duo Milli Vanilli alongside the late Rob Pilatus.

While Pilatus died in 1998, Morvan confirmed that he would perform at the festivities, organized by Freedom 250, the “national, non-partisan organization leading the celebration of our Nation’s 250th birthday” established by Trump.

“I am here to entertain and unite people, not divide them,” Morvan said. “Let’s celebrate life & music and take a trip down memory lane. I feel honored to be a part of it as it will celebrate the 250 Year Anniversary of America with so many other accomplished artists.”

Morris Day, meanwhile, was one of the first to announce he would not appear at the event. He took to social media hours after the lineup was announced, writing that “Morris Day and the Time will not be performing at the Great American State Fair,” despite rumors to the contrary. McBride followed suit, telling fans she’d been under the impression the event was nonpartisan.

“That turned out to be misleading,” McBride wrote in an Instagram post. “I asked lots of questions and was assured this was a nonpartisan event that was meant to celebrate ALL 50 states.”

She added that “it greatly upsets me that any fan who has been moved by my music may feel I was abandoning the meaning behind those songs.”

The Commodores echoed the sentiment — writing that their music is not affiliated “with any single political party” — as did Young MC.

“The artists were never told about any political involvement with the event,” Young MC wrote. “And despite the claims by the organizers that the event is non-partisan, SPIN magazine describes it as Trump-backed.”

On Friday, Bret Michaels also revealed he would not be performing, becoming the latest musician to announce his exit.

“Unfortunately, what was presented to us as a celebration of our country has evolved into something much more divisive than what I agreed to be a part of,” Michaels wrote.

He also cited safety concerns involving his fans, band, crew and family.

C+C Music Factory vocalist Freedom Williams similarly said that when he was contacted about the summer show, there was no mention of Trump.

And despite Morvan’s commitment to the performance, Milli Vanilli in a statement said the band’s original vocalists — including Jodie Rocco, Linda Rocco, Brad Howell, John Davis and Charles Shaw — would not attend.

“Others using the name ‘Milli Vanilli’ that appear on the advertisement should be considered a tribute band with no association vocally or musically to our sound or songs,” it said in a statement.

In 1990, Milli Vanilli, famous for hits like “Girl you Know it’s True,” and “Blame it on the Rain,” won a Grammy, but their award was ultimately rescinded after it was revealed that Morvan and Pilatus had been lip-syncing.

The Great American State Fair is scheduled to run June 25-July 10.
