Australian and international entertainers, from the past and present, have paid tribute to John Farnham in a concert raising funds for head and neck cancer.
Thousands filled Melbourne's Rod Laver Arena for the sold-out show, with many more watching around the country as the concert was beamed to select cinemas live.
The concert marks the beginning of the Lend Your Voice campaign to raise $1 million for Head and Neck Cancer Australia over the next year, with Farnham partnering with the organisation that helped support him through his own journey with cancer.
Wilkins said Farnham had sold out 94 shows at Rod Laver Arena over the years, the most of any performer ever.
Farnham himself was not able to attend the concert, with his family confirming that the 77-year-old's health had declined recently.
The concert began firing on all cylinders, introducing an all-star opening line-up of Jessica Mauboy, John Stevens, Jack Jones, Mahalia Barnes and Human Nature to sing a medley of Farnham songs, including the title track to 1988's Age of Reason, 1986's Reasons and 1996's Have a Little Faith.
The Farnham clan was still represented onstage, with John's son Rob Farnham singing Love To Shine from the album Whispering Jack.
The concert also paid tribute to Farnham's theatre career, including his 1992 turn in the title role of Jesus Christ Superstar.
Dion said she sang this song as a duet with Farnham during her last visit to Melbourne and launched into You're The Voice, bringing the crowd at Rod Laver Arena to its feet.
