Woodstock 50 says it has a new backer to ensure the 2019 festival goes on as scheduled in Upstate New York, but there may still be chaos behind the scenes.

Sources tell Billboard that Woodstock co-founder and 50th anniversary organizer Michael Lang needs to raise $30 million by this Friday to ensure Woodstock 50 happens on Aug. 16-18 at Watkins Glen International raceway. A spokesperson for Lang said that CID Entertainment has agreed to replace Superfly as the festival’s producer, but CID boss Dan Berkowitz has not confirmed its involvement.

It’s unclear if CID would be able to provide $30 million in funding, which is in addition to the $30 million that original investor Dentsu Aegis Network has already spent for the three-day event. Much of that money went to pay artists in full, including big names on the lineup like Jay-Z, Santana, Miley Cyrus, The Killers, Chance the Rapper, John Fogerty, Janelle Monae, Dead & Company and Imagine Dragons.

Dentsu, a Japanese investment company, said last week that Woodstock 50 was canceled because it didn’t “believe the production of the festival can be executed as an event worthy of the Woodstock Brand name while also ensuring the health and safety of the artists, partners and attendees.” Dentsu said it was worried after capacity for Watkins Glen was reduced from initial figures of 150,000 to half: 75,000.

Billboard reported Dentsu pulling out also voided the contracts with all performers, who’ve now been paid but are not obligated to appear at the festival.

Lang says Dentsu doesn’t have the right to cancel Woodstock and has hired lawyer Marc Kasowitz, who served as a personal outside attorney for President Donald Trump and briefly represented him in Special Counsel Robert Mueller’s Russia investigation.

Rolling Stone reports Lang is holding Dentsu responsible for all the issues delaying Woodstock 50, claiming the company blocked ticket sales "for no apparent reason.”

Tickets were scheduled to go on sale April 22 at a three-day-pass-only price of $450, but sales were delayed due to a late mass gathering permit application sent to the New York State Department of Health just a week earlier on April 15. The state says the permit is still pending.

Lang also claimed Amplifi Live, an investment arm of Dentsu Aegis, “illegally swept approximately $17 million from the festival bank account, leaving [Woodstock] in peril.” Rolling Stone reports he also alleged Dentsu directed other companies, including Watkins Glen International and other vendors, to sever ties with Lang and encouraged artists to back out to ensure a spot performing during the 2020 Summer Olympics in Tokyo, where Dentsu organizes events.

If Lang doesn’t raise $30 million by Friday, it’s unclear if Woodstock 50 will continue.

More than 400,000 people attended the first Woodstock festival, held Aug. 15-18, 1969, at Max Yasgur’s dairy farm near White Lake in the Catskill Mountains. Performers included Richie Havens, Jefferson Airplane, The Who, Joan Baez, Jimi Hendrix, Santana, Joe Cocker, the Grateful Dead and Crosby, Stills, Nash & Young.

The iconic concert was revisited in 1994 with a modern lineup of artists like Nine Inch Nails, Sheryl Crow, Metallica, Cypress Hill and Red Hot Chili Peppers in Saugerties, but Woodstock ’99 -- held at Griffiss Air Force Base in Rome, N.Y. -- was marred by riots, fires and allegations of sexual assault. Lang helped organize both anniversary events.

The original Woodstock site is planning its own anniversary celebration on the same weekend. The Bethel Woods Center for the Arts will host Arlo Guthrie and a screening of the “Woodstock” documentary on the field Thursday, Aug. 15; Ringo Starr, Guthrie, and The Edgar Winter Band on the pavilion stage Friday, Aug. 16; Santana with the Doobie Brothers on Saturday, Aug. 17; and John Fogerty on Sunday, Aug. 18. Guthrie, Winter, Santana and Fogerty all performed at the original Woodstock festival.
