Elton John told The Sun, "I'm lucky to be alive."

The music legend postponed his summer tour after a potentially fatal appendix abscess.  John explains that he played nine shows in pain, but it became too much for him during his Friday concert in Germany.

A source told The Sun, "Elton is over the worst but is still very sick. It’s been a horrible ordeal.”

According to doctors, an appendix abscess is worse than typical appendicitis.  Though not as bad as dealing with a burst appendix, it can still take months for a patient to recover.

Elton John is not scheduled to perform again until September.
