But it seems to be purely precautionary
Allman has revealed to Billboard.com that he's having to cancel some of his scheduled book signings because he is due to undergo tests Friday at The Mayo Clinic in Jacksonville, Fla
"It's just one of those make-sure tests, you know," Allman said. "My heart goes into A Fib (atrial fibrillation) and does those beats - you know, instead of going du-dun, du-dun, du-dun, it goes ta-da-dat-ta-da-doot-doot. There's a little reggae in there somewhere."
The heart problems are likely related to the liver transplant which Allman underwent in 2010. He's had a few setbacks since that operation, with a hernia operation during a run of Allman Brothers shows at the Beacon Theater in New York the most recent.
Allman will begin his book tour May 8 if doctors turn up no significant problems. He also plans to hit the road this summer with the Allman Brothers, something he feels he owes his fans.
"I know there's been a lot of people that have had their hearts set - God bless `em - on seeing me and my boys perform and seeing me and the Brothers perform," Allman said. "And because of this virus and all these damned surgeries, I had to cancel. I've always really held that sacred and a no-show I am not. I'd like extend my apology to them. It's just kind of a bigger bump than I expected in the road, and as of this summer I'll be there with bells on in the future."
