Gregg Allman announced on April 26 that he was delaying his upcoming book tour for his new memoir "My Cross to Bear" because he needed to undergo tests on his heart.
"It's just one of those make-sure tests, you know," Allman told the Associated Press. "My heart goes into A Fib (atrial fibrillation) and does those beats."
Allman, who co-founded of The Allman Brothers Band, is scheduled to undergo tests on April 27 at The Mayo Clinic in Jacksonville, Florida. In 2010, Allman had a liver transplant due to Hepatitis C has been steadily recovering since.
In the past he's been occasionally forced to cancel or postpone performances because of setbacks from his health. He also recently had hernia surgery related to the transplant. It is unclear if his heart problems are related to the transplant
Gregg Allaman's brother Duane Allman, who was the band's other co-founder, died in a motorcycle accident in 1971, just months after they released their breakthrough live album "At Fillmore East."
Allman will begin his book tour May 8, if doctors give him a clean bill of health. He will also hit the road this summer with the Allman Brothers.
"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."
