Elton John is suffering from appendicitis and will postpone all concerts until he has fully recovered from surgery, it was announced Tuesday.
Turns out the "Tiny Dancer" singer has an abscess on his appendix, a condition discovered when tests were run after he fell ill during his current tour. He is expected to undergo surgery soon, once toxins from the abscess are reduced, according to a rep.
"Elton is incredibly disappointed to postpone these tour dates," the spokesman said on John's official website. "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 on top form and return to play the remaining shows starting in early September 2013."
The 66-year-old was to have headlined a show in London's Hyde Park this Friday, and toured Europe through July. His website's tour page currently lists no shows before early September, but he's down to play 14 dates in Las Vegas from Sept. 18 through Oct. 12.
