Country musician John Anderson was recovering from surgery after suffering a heart attack at a Charleston, W.Va., hotel over the weekend.
He was hospitalized in stable condition Monday, said publicist Jim Della Croce.
Anderson, 48, was to perform at the Charleston Sternwheel Regatta on Saturday night but was taken to the hospital that afternoon.
"The production group told me he tried to leave the hospital twice because he'd never missed a show before," said the festival's director, M. Sharon King.
Anderson had been having chest pains, said Della Croce. The singer had an angioplasty and a stent was placed in his heart during surgery, Della Croce said.
"He's in good spirits," the publicist said. "He's expected to be released later in the week."
Anderson's 1983 hit "Swingin"' — the largest-selling country single in Warner Bros. history — was named best single of the year by the Country Music Association. His album "Seminole Wind" went double platinum in 1992.
In 1993, Anderson, who lives in Smithville, Tenn., won an Academy of Country Music Career Achievement award.
Anderson's touring schedule is suspended for the time being. Della Croce said an announcement about future performance dates will be made mid-week.
