The Wiggles have announced that three of their members will retire after this year's tour.
The children's group has announced that Greg, Jeff and Murray will perform together for the final time in a farewell tour that will kick off at the end of the month and end in Australia in December.
But Wiggles said they had hired new members who would carry on their legacy.
"We've been entertaining children around the world for 21 years and it’s important that we plan for the future so that The Wiggles can keep wiggling in the years to come," Murray said in a statement.
The blue Wiggle, Anthony, will remain in the band.
The departing band members will stay involved with The Wiggles, performing creative roles out of the limelight.
The band's farewell tour will see them visit the UK, USA, Canada and New Zealand.
The tour will commence in Australia in November and December.
"The touring and performing over the past 21 years has meant that we've spent a long time away from our own families and friends," Murray said.
"We miss them and want to spend more time at home which is a major reason why three of us decided it was time to hand on our skivvies to a new generation."
The group has revealed their replacements as Emma, Lachy and Simon, who will join the band on their final tour.
"Lachy, Simon and Emma all have wonderful singing voices and are experienced children's performers," Anthony said.
"They have worked with us for several years, playing various characters including Wiggly dancers, Dorothy the Dinosaur, Captain Feathersword and Wags the Dog."
Lachy said he was delighted to become a Wiggle after working with the band for three years.
"Emma, Simon and I can't wait to get out there in our skivvies next year and continue the fun Anthony, Jeff, Murray and Greg kicked off 21 years ago," he said.
The Wiggles have toured around the world and sold over 23 million DVDs and seven million CDs since releasing their self-titled debut album in 1991.
