While Elton John is knee-deep in promotion for his musical documentary Never Too Late (premiering on December 13 on Disney+), he has also not released any new music lately. That’s because the singer has been struggling with some major health issues regarding his vision.

The “Rocket Man” singer revealed in September that a severe eye infection had left him with “only limited vision in one eye.” At the time, John told his Instagram followers that he was healing but that it was “an extremely slow process” and it would “take some time before sight” would return to his eye.
