The promoter of an Old School" concert in Atlanta has apologized after ticket holders called the show a "disaster" and demanded refunds.

People who attended the "Saturday Nite Old School Music Festival 2021" at Home Depot Backyard in Atlanta on Sept. 11, expected to see Johnny Gill (pictured), The Commodores, and Frankie Beverly & Maze.

Other artists in the lineup included Kool & the Gang and The Whispers.

The crowd started booing when Johnny Gill finally emerged onstage and told them he wasn't performing.

People who left the concert early complained that they did not get what the promoter promised.

Many said the concert began two hours late and unknown artists took up a lot of time on stage.

The promoter of the show, SEMG, has issued a statement apologizing and promising "partial refunds" on a case-by-case basis.

The promoter told Channel 2's Tom Jones that he is considering offering partial refunds.

However, when Jones set up an interview with the promoter to give him an opportunity to give his side of the story, he never showed up.

He also stopped answering the phone calls and texts from Jones.

"This was one of the biggest rip-offs I've ever seen," concertgoer Reggie Nelson told Jones.

Other concertgoers include the wife of Shelley Wynter, co-host of WSB Radio's "Word On the Street," who received her ticket as a gift from her husband.
