Early last month, Gregg Allman was forced to cancel a string of tour dates due to a “serious health issue,” and ahead of his return to the stage this weekend at his own Laid Back Festival at Red Rocks, Allman has discussed his illness in an interview with Westword (via Live for Live Music).

“Right in the middle of the thing I got pneumonia,” Allman says. “Yeah, that was a drag. I was almost to the end of a tour. I had to two more to go, and damn, it just set in. I had to postpone two of the gigs, but we’ll go back and make them up, for sure.”

In a press release earlier this month, Allman announced that his doctors had given him a clean bill of health to return to the stage at Red Rocks. “I just can’t wait to get back out there,” Allman said in the release. “I’ve gotten so stir crazy these last few weeks. I feel best when I’m traveling and playing. That’s what keeps me going, and there’s no better place to start than Red Rocks.”

Along with the Red Rocks show this Sunday, Allman will also appear at the Laid Back Fest in Atlanta on October 29 and will play a 10-night residency at New York’s City Winery starting November 6.
