Elton John’s spokesperson has confirmed to ET Canada the singer is suffering from appendicitis and has cancelled his Hyde Park concert scheduled for this Friday.

After his recent  European tour, the Grammy-winning star fell ill and he underwent a number of exploratory scans which led to a diagnosis of appendix abscess surrounding retrocaecal appendicitis.

The legend, who regularly performs in excess of 120 concerts per year, is currently  undergoing a course of intensive antibiotics and is expected to undergo surgery in the UK in the coming weeks, once doctors can be confident they have sufficiently reduced toxins within the inflamed appendicitis site.

Sir Elton, 66, has been advised by his doctors and surgical team to postpone all forthcoming shows from his current European tour, including his Hyde Park concert which is part of the Barclaycard British Summer Time Festival running this month. 

Elton’s spokesperson confirmed he won’t resume touring until he has fully recovered from both the planned surgery and any damage caused by the appendix abscess, and tells us: “Elton is incredibly disappointed to postpone these tour dates. 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.”;
