“Mony Mony” singer Tommy James stopped his Las Vegas show early.

On Friday, March 7, the longtime rocker, 77, halted his concert at The Showroom at the Golden Nugget casino due to “exhaustion.”

The Tommy James and the Shondells frontman is said to have stopped singing about an hour into the show when he was heard struggling to breathe.

Carol Ross, James’ representative, tells PEOPLE the musician suffered “exhaustion from a long flight, sound check and the show all in one day.”

“He is fine now and back home in New Jersey,” she adds.

Bill Freeze, an audience member, wrote on Facebook that James “was breathing heavily” and “tried to sit down on a wooden box that was on the stage.” The singer then reportedly attempted to adjust his microphone when he was “immediately helped off stage.”

Freeze stated that a medical team “rushed to help him.” The concert reportedly ended early due to the incident.

Las Vegas Review Journal reported that the incident occurred during his performance of his 1968 hit “Do Something to Me,” shortly before his encore.

The venue told the outlet that paramedics and security treated James on-site and he departed the following morning.

James’ next scheduled performance is on March 15 in Tulsa, Okla., according to his website. He has more tour dates planned throughout the year. He will be back at the Las Vegas venue on Oct. 17.

In a June 2024 interview with Jersey Sound, the rocker reflected on his long career, saying, “I look at my career and I see how I’ve been so blessed in so many different ways. And that’s really the truth. The idea of actually doing what I love doing for this long, and the fans moving right along with me.”

James has released 12 solo studio albums from 1970 to 2016, as well as eight with Tommy James and the Shondells. The band’s song “Crimson And Clover” peaked at No. 1 on Billboard’s Hot 100 in 1969 and spent 16 weeks on the chart.

The singer performed the hit song at the 2015 Rock and Roll Hall of Fame Induction Ceremony with Joan Jett & the Blackhearts, who famously covered the song in 1982.

“It’s meant a lot,” James told Billboard of Jett’s cover. “She had a No. 1 record with it, just like we did, and it has ended up being probably the biggest-selling single we ever had, so I’m thrilled. I’m thrilled to be here.”

In July 2019, Variety reported that James and film producer Barbara De Fina were developing a biopic based on his autobiography Me, the Mob and the Musicv
