A federal judge has granted the estate of Isaac Hayes a special hearing on its $3 million claim against Donald Trump, who repeatedly used the song “Hold On, I’m Coming,” co-written by Hayes, during the election campaign.

Earlier this month, Hayes’ estate filed a cease-and-desist letter seeking $3 million in connection with Trump’s unauthorized use of the Sam & Dave classic, which the estate’s lawyer counted has been played “over a hundred times” at Trump rallies since 2022.

In an August 10 tweet, the singer’s son, Isaac Hayes III, wrote: “Today, on the anniversary of the death of my father Isaac Hayes, we have repeatedly asked Donald Trump, the RNC and its representatives not to use the song ‘Hold on I’m Coming’ written by Isaac Hayes and David Porter at campaign rallies, but in Montana they used it again.”

Hayes III added, “With his disrespect and sexual abuse of women and his racist rhetoric, Donald Trump embodies the worst in integrity and class,” and warned, “We will now deal with this very quickly.”

The estate and its attorney, James Walker, weren’t kidding when they said “very quickly.” They managed to deliver the documents to a Trump campaign office in Delaware, setting the ball rolling for a preliminary injunction hearing in an Atlanta court shortly after Labor Day.

“The Federal Court has granted our motion for an emergency hearing seeking a preliminary injunction,” Hayes III tweeted Saturday. “Donald Trump, the RNC, Trump, Trump for President Inc. 2024, Turning Point and the NRA are scheduled to appear in Northern U.S. District Federal Court in Atlanta on September 3, 2024.”

Trump has made the unauthorized use of popular music one of the hallmarks of his political career. Just this month, Celine Dion asked him to stop playing “My Heart Will Go On.” In the past, he has received similar complaints for using songs by Tom Petty, Rihanna, the Rolling Stones, the Village People, John Fogerty, Aerosmith, Linkin Park and Journey. Last week, he added Foo Fighters and Beyoncé to his hit list.

The letter from Hayes’ successors also states that Trump’s demand to shell out $3 million for all these unauthorized reproductions is actually “a very small amount than the normal royalty fee for so many multiple uses. The normal fee for these violations will be ten times as high if we sue, starting at $150,000 per use.”

Trump had until August 16 to respond to the letter. After that deadline, the estate administrator turned the letter into a legal matter, leading to a special hearing on September 3.
