Listen to Elton John on iHeartRadio

Elton John is postponing some tour appearances due to a bout with appendicitis.  Sir Elton is undergoing a course of antibiotics and will have surgery to fix his condition.  The 66 year-old rocker won't resume his tour until he is fully recovered. 

A spokesman for the music legend said Sir Elton is incredibly disappointed to postpone his tour, but he hopes to be back on the road in early September. 

The schedule posted on his website has him returning to the stage in Leeds, England on September 4th.
