Lady A’s Charles Kelley is giving an update about his health, saying how disappointed he and the group were to have to cancel their Saturday night concert at Lakefront Music Fest in Minnesota after Kelley was rushed to the hospital with appendicitis.

Kelley’s bandmates, Hillary Scott and Dave Haywood, first broke the news over the weekend, saying:“after such a long wait, there isn’t much that could keep us from being with our fans,” adding that they planned to return to the road “the minute [Kelley] is cleared by his doctors.”

Kelley offered an update from his hospital bed, sharing on Instagram: “Hey guys – sitting here in the hospital and so bummed to have missed performing our first show back in Minnesota, not to mention in 16 months – that’s an understatement. But the ol’ appendix had other plans. didn’t even know what an appendix was until friday when it sent me to the ER. Love y’all and be back soon enough.”
