Two singing superstars -- Elton John and Randy Travis -- have been sidelined by medical conditions.
Sir Elton John
Sir Elton John, 66, has been diagnosed with an appendix abscess that requires surgery, People reports.
The affliction has forced him to postpone all upcoming shows on his European tour, including a concert Friday in London's Hyde Park alongside Elvis Costello and Ray Davies.
"Elton is incredibly disappointed to postpone these tour dates," says his rep. "To know that he made such super-human efforts and continued to perform to thousands through his illness only confirms his dedication to his European fans. He is eager to be back in top form and return to play the remaining shows starting in early September 2013."
According to his rep, the legendary musician called in a team of doctors after feeling ill during his recent European tour. He went through a battery of scans and blood tests before being officially diagnosed with "appendix abscess surrounding retrocaecal appendicitis."
Mr. John is taking a course of intensive antibiotics and is expected to undergo surgery in the coming weeks, once doctors are sure they have sufficiently reduced toxins within the inflamed appendicitis site, says his rep.
Mr. John certainly won't be bored while recuperating at home.
He and partner David Furnish, 50, are raising sons Zachary, 2 1/2, and Elijah, who will be six months old Thursday.
Travis in critical condition
Randy Travis, who has been hospitalized in Texas since Sunday, did not get heart surgery. But he did get a serious medical procedure affecting his heart.
The country singer "underwent placement of an Impella peripheral left ventricular assist device for stabilization prior to transferring hospitals," his rep confirmed to People in a statement Tuesday. "Travis remains in critical condition."
There was also a message for the singer's fans: "We are very thankful to the fans for their love and support during this time."
The Impella device is inserted via a catheter, so it's not technically surgery, but it's still serious.
On Monday, Travis' sister-in-law, Teresa Traywick, told People he went under the knife.
"We have been told he has had surgery," Ms. Traywick, the wife of Randy's brother Ricky Traywick, said at the time. "Our prayers are going out to him because my husband just had a heart attack last year, so it is in their family."
She added that Randy and Ricky's mother "passed away at an early age with her heart, so it is like these boys are following right in their footsteps."
Mr. Travis, 54, is "suffering from complications of recently acquired viral cardiomyopathy," a rep for the Grammy winner has said. Viral cardiomyopathy is a weakening of the heart muscles due to infection.
He was scheduled to play the Deadwood Mountain Grand in Deadwood, S.D., today, but that show has been canceled.people
