John Farnham reunited with Olivia Newton-John at the Fire Fight Australia bushfire relief concert in Sydney on Sunday night.

Farnham, 70, performed three songs and a duet with the iconic Grease star before allowing Mitch Tambo to join him in performing his legendary hit You’re The Voice.

Tambo received a standing ovation as he sung the lyrics in his Indigenous Gamilaraay language. He starred on the 2019 season of Australia’s Got Talent and gave it his all as Farnham watched on in pride.

Proving to be a night to remember, Farnham, Tambo and Newton-John were also joined on stage by Queen’s guitarist Brian May, 72.

Farnham kept his fans happy with iconic performances of his songs Pressure Down, That’s Freedom, Age of Reason and performed Two Strong Hearts with Newton-John, 71.

Newton-John turned heads as she emerged on stage in a chic but casual outfit.

Fans were thrilled by a heartfelt moment where a number of male and female firefighters were also ushered on stage in order to be recognised for their amazing efforts during the bushfire crisis. 

The ten-hour charity event resulted in $9.5 million being raised for bushfire relief efforts.
