A visibly upset Sir Elton John has been forced to cut short a concert in New Zealand after falling ill with walking pneumonia.

Axar.az reports citing foreign media.

The musician, 72, lost his voice mid-way through his set at Auckland's Mount Smart Stadium on Sunday.

"I've just completely lost my voice. I can't sing," Sir Elton told the crowd. "I've got to go. I'm sorry."

Sir Elton appeared to break down in tears as he leaned on his piano and shook his head.

The audience gave the English singer a rapturous ovation as he walked gingerly off stage, helped by several assistants.

Earlier in his set, Sir Elton told the sold-out crowd he had been diagnosed with walking pneumonia on Sunday.

The concert was the first New Zealand show of Sir Elton's Farewell Yellow Brick Road tour.
