Neil Finn has made his official debut as part of Fleetwood Mac, after the band fired leading songwriter Lindsey Buckingham earlier this year.
The Crowded House frontman was front and centre alongside singer Stevie Nicks, as the band performed their classic hits The Chain and Gypsy on Wednesday's episode of popular US daytime show Ellen.
Finn and former Tom Petty and the Heartbreakers guitarist Mike Campbell joined the classic rock band in April after reports Buckingham had been "fired" over a touring disagreement.
While drummer Mick Fleetwood later sought to downplay Buckingham's departure as "a marriage that came to an end", the revered guitarist, who had been with Fleetwood Mac since 1974, said leaving was "not my doing or my choice".
While Finn's number lacked the legendary subtext that fuelled much of Fleetwood Mac's performances in the past, with Nicks and Buckingham often reeling off bitter lines based on their own romantic past, host Ellen praised the new lineup.
"I can't believe how good you all sound, it's so exciting to hear you," she told the band.
Finn thanked his followers on Twitter for their support regarding his Mac debut.
"Thanks for the many warm messages of goodwill, welcome, concern, bemusement, wonder," he wrote.
"I love being in Fleetwood Mac."
The new-look lineup is set to embark on an extensive North American tour from October into April 2019.
