Greg Page, the original lead singer of the Wiggles, collapsed at the band’s Australia bushfire relief charity concert in Sydney Friday.
The Wiggles’ Twitter account confirmed Page had been taken to hospital where he was receiving treatment.
The band then confirmed he’d suffered a cardiac arrest and was now recovering:
Page had been performing in the reunion gig alongside his original Wiggles bandmates Anthony Field, Murray Cook, and Jeff Fatt when he reportedly fell to the ground as he walked off stage.
According to ABC News Australia, New South Wales Ambulance confirmed “a man in his forties was taken to Westmead Hospital in a serious but stable condition.”
Following the weekend’s events, the group updated fans Twitter Monday morning on Page’s condition.
The children’s music group, who shot to fame in 1991 before revealing a new lineup in 2013, carried out an encore performance of “Hot Potato” without Page.
The performer retired from the band back in 2006 due to illness and was diagnosed with orthostatic intolerance. He then returned to his role as the Yellow Wiggle in early 2012, before the band retired together later that year.
