Elton John has said he was "deeply upset and sorry" for cutting short a concert in New Zealand after being diagnosed with walking pneumonia.
The music star (72) was performing at Auckland's Mount Smart Stadium yesterday when he lost his voice and broke down in tears on stage.
In footage shared by fans on social media, John is seen crying as he is escorted from the stage while thousands of concert-goers give him a standing ovation.
John posted on Instagram a short while later: "I want to thank everyone who attended tonight's gig in Auckland.
"I was diagnosed with walking pneumonia earlier today, but I was determined to give you the best show humanly possible. I played and sang my heart out, until my voice could sing no more."
According to one fan on social media, John had told the audience earlier in the show: "My voice has completely gone, I'm so sorry."
He was tended to by a medic for around five minutes earlier in the set and continued to play before he was forced to stop completely.
According to the American Lung Association, walking pneumonia is a "non-medical term for a mild case of pneumonia".
Generally called atypical pneumonia, it can be caused by bacteria or viruses and symptoms, including a cough, fever, chest pain, mild chills and a headache, are similar to that of a bad cold. Symptoms are usually mild enough for a sufferer to be able to continue their daily activities.
