The change to the Australian national anthem tripped up indie singer Gordi, who inadvertently performed the previous version of 'Advance Australia Fair' which was tweaked slightly in January.
The 28-year-old accidentally performed the old 'for we are young and free' lyric, which was changed earlier in the year to 'for we are one and free' out of respect for Indigenous history.

Despite the gaffe, the a capella performance of the anthem sounded great as it echoed around Rod Laver Arena - however the error did prompt some criticism of Gordi online.
The change to the anthem was announced by Prime Minister Scott Morrison on New Year's Eve, after Governor General David Hurley agreed to a recommendation provided by the federal government.

“Young and free”? I thought we were “one and free” now. #AusOpen

And that’s the old version of the anthem. We are one, not young. #AusOpen

“During the past year, we have showed once again the indomitable spirit of Australians and the united effort that has always enabled us to prevail as a nation. It is time to ensure this great unity is reflected more fully in our national anthem,” Mr Morrison said.
“Also, while Australia as a modern nation may be relatively young, our country’s story is ancient, as are the stories of the many First Nations peoples whose stewardship we rightly acknowledge and respect.
“In the spirit of unity, it is only right that we ensure our national anthem reflects this truth and shared appreciation.”
Gordi's path to performing at the Australian Open final was a unique one among performers, as she put her music career on hold at the beginning of the coronavirus pandemic to work as a junior doctor.
The anthem performance followed a head-scratching pre-game performance from the Australian cast of musical Come From Away, which is based on a flight forced to land in Canada during the September 11 attacks.
The musical tells the story of the roughly 7000 passengers who were stranded in the small town of Gander when flights were grounded.
Novak Djokovic wins ninth Australian Open
Hitting back at his detractors and slamming the doubters, Novak Djokovic says his ninth Australian Open triumph was among the most challenging of his grand slam career.
Djokovic thumped Daniil Medvedev 7-5 6-2 6-2 in Sunday night's final before taking aim at his critics.
The Serb was savaged pre-tournament for detailing a list of so-called quarantine demands for the 72 players holed up in hard lockdown, then accused of exaggerating an abdominal injury during his five-set third-round win over Taylor Fritz.
"Emotionally (this) was one of hardest tournaments I had, to be honest, with quarantine and a lot of things happening in the media," the world No.1 told Nine.
"The letter that I wrote, ideas and recommendations that I got from players was misinterpreted as my request and list of demands.
"Then the next thing you know within a couple of days I'm persona non grata in this country.
"I got injured in the third round. It was a rollercoaster ride if I can define it in one word. I think it makes it even sweeter for me."
Djokovic maintained he tore a stomach muscle against Fritz, and that the injury still hadn't fully healed.
