Sir Elton will do a live cross to Telethon from his Rocket Man 40th anniversary concert at Perth Arena.
After several months of negotiations, Telethon organisers celebrated confirmation that the singer would play two songs live from his Perth concert to the Statewide Telethon audience.
Telethon general manager Steve Mummery said the show would cross to the rocker's concert spectacular on Saturday November 10.
"Elton has agreed to perform two songs exclusively for Telethon at his concert," he said.
"We'll cross to the concert live for a couple of songs.
"It's pretty exciting to have somebody of the calibre of Elton John on Telethon.
"He has a child himself and knows how important it is for us to be looking after our kids.
"It's going to be a great event and fantastic for Telethon."
Elton is the opening act for the new 15,000 seat Perth Arena.Telethon
