Yellow Wiggle Greg Page collapses during bushfire relief concert - Sydney Morning Herald

Greg Page, one of the founding members of The Wiggles, has collapsed in Sydney while performing at a bushfire relief concert.

The Wiggles said a "medical incident" involving Page occurred off-stage as the original band members performed at Castle Hill RSL on Friday night.

"Medics were called immediately and he was taken to hospital where he is receiving treatment. We will provide more information as it comes to hand," the band said in a statement after the show.

A NSW Ambulance spokeswoman said a 48-year-old man was taken to Westmead Hospital in a serious but stable condition from the Castle Hill RSL.

Footage from the concert shows Page, who suffers from a circulatory system disorder, singing and dancing on stage just moments before he collapsed towards the end of the show. The sold-out over-18s reunion show was being livestreamed at the time, with all proceeds going to the Australian Red Cross and WIRES.

"Thank you everybody," Page says, waving to the crowd and smiling.

"Thanks for coming to support all of those wonderful people doing all that great work for everyone."

As the crowd cheers, Page walks to the side of the stage and collapses.

Several people can be seen running across the stage and the stage curtain is partially pulled across to shield him from the audience.

Murray Cook, the original Red Wiggle, then returns to the stage to speak to the crowd.

"Guys I think we're going to end it there. Greg's not feeling real well. I think he's going to be OK but he's not feeling real well so I don't think we can go on with another song," he says.

The band members do, however, return to the stage a short time later and perform the song Hot Potato.

"We're going to sing it for Greg and hope he gets better real quick," blue Wiggle Anthony Field says.

Page has spoken publicly before about suffering from orthostatic intolerance, an often undiagnosed circulatory system disorder that affects blood flow.

In his memoir Now and Then: The Life-Changing Journey of the Original Yellow Wiggle, Page talks about how the illness forced him to leave the Wiggles in 2006, after 15 years of touring the world with his best friends.

People with the condition lack a nervous system that adequately moves the blood around their body, so that when they sit or stand for any length of time, blood instead pools in their pelvis or leg regions, causing them to faint.

For more than a decade, Page suffered embarrassing symptoms that made him worried others might think he was drunk. He often felt disoriented and vague, dizzy when standing upright for long periods and even slurred his words. He sometimes walked into walls and missed his mouth when he tried to eat dinner.

"I became almost a social recluse, incapable of communicating at any great level with anyone,'' he writes of how it affected him. ''It would exhaust me just to think, let alone talk or walk.'

"I wanted to give more attention to this condition, to help people diagnose it and [deal with] the frustration that comes with being misdiagnosed."
