Bass player Dave Sirmon dies unexpectedly on Mark Chesnutt's tour bus

Dave Sirmon, bass guitarist for country singer Mark Chesnutt, died in his sleep on the tour bus Saturday night. Chesnutt, 62 and currently on the road, confirmed the loss Monday on Instagram, calling Sirmon his "buddy" and a musician he depended on for far more than playing bass. Sirmon's wife, Louise, posted the confirmation on her husband's Facebook page a day earlier.

Chesnutt's tribute

The "Brother Jukebox" singer wrote that Sirmon, a "great musician and friend," was someone he could rely on for every dimension of life on the road. "Advice, music, songs, the bus. Everything," Chesnutt wrote. He described Sirmon as a hard worker, very hands-on with road operations.

Chesnutt called Sirmon one of the most positive people he had ever known. Quiet by nature, Sirmon carried a reputation for sharp humor. Chesnutt wrote that he never heard him complain once, and that seeing him always brought an immediate smile: "When you saw Dave, you saw light." He closed the post by calling Sirmon "the perfect country gentleman and an amazing man" and said Sirmon would always ride with the band in spirit and in heart.

Louise Sirmon's confirmation and the community response

Louise Sirmon confirmed on her husband's Facebook page that Dave James Sirmon had passed away in his sleep on the tour bus. She wrote that she was sorry to anyone learning of the news through social media and said memorial plans would not be in place for several weeks, though she would share details once they were finalized.

On Sunday, a friend posted a separate appeal on Facebook, asking those who knew Sirmon to consider donating to Louise as she manages the financial burden of unexpected expenses. The post described Sirmon as someone who opened his home and life to others, with room at his holiday table for friends, strangers, and anyone who needed a place to belong. It noted that he was "deeply loved throughout the country music community and by countless friends whose lives are better because they knew him."

What to watch

Louise Sirmon said she will share memorial plans once arrangements are in place. No date has been confirmed.
