(WISH) — The singer of “Every Rose Has Its Thorn,” “Talk Dirty to Me” and “Nothin’ But a Good Time,” Bret Michaels, has postponed his Aug. 12 concert at the Indiana State Fair to 2027 due to health complications.

It’s the second show to be postponed to 2027 at this year’s fair, which begins Aug. 7. The Beach Boys were set to perform at the Free Stage on opening day. Instead, The Spinners and The Four Tops on the Free Stage on opening day, the fair’s website says. The fair website also says another show for Aug. 12 is “to be announced.”

The rocker’s website said he is recovering from urgent surgery for a complicated obstructing kidney stone. A ureteral stent placed during the procedure will remain in place for three to four weeks as part of his post-operative recuperation.

Michaels experienced severe kidney pain following a recent performance honoring military heroes and their families at Fairchild Air Force Base in Spokane, Washington. On July 19, he was diagnosed with the kidney stone and received immediate surgery.

Michaels’ lifelong Type 1 diabetes further complicates his recovery, the website said. His doctor noted that the condition impairs healing and compromises the immune system, putting Michaels at an exceptionally high risk of contracting a serious urinary tract infection or developing urosepsis — a blood infection — until the stent is removed.

Michaels said in a statement, “I’m forever grateful for the amazing medical treatment and ongoing medical attention throughout my personal life and career. I’m truly grateful for family, friends, fans, band, crew and promoters for their understanding. If all goes well, I will hit the road late August with 1000% energy, intensity and truly nothing but a good time.”
