Australian artist John Williamson penned the lyric in his famous song True Blue some 43 years ago.
But as Williamson sang at Adelaide Oval on Wednesday ahead of the third Ashes Test, his lyrics assumed fresh poignancy.
Williamson's latest performance of True Blue came on a day when the first funerals were to be held for the 15 innocent victims killed in last Sunday's shooting at Sydney's iconic Bondi Beach.
"I firmly have the view we've got to keep putting one step after the other and use cricket as a unifying voice," Cricket Australia's chief executive Todd Greenberg told reporters in Adelaide.
"(It's) a real moment in time, particularly with John Williamson playing.
"We moved really quickly to make that happen and I'm really glad he's doing it because it will be a special moment for cricket but also for the country."
Williamson's rendition came as shockwaves from the Bondi shooting continued to reverberate.
Adelaide Oval's flags flew at half-mast; Australian and England cricketers wore black arm-bands as the freshly dubbed 'Christmas Test' began as anything but a celebration.
An increased police presence patrolled outside the hallowed sporting venue, some officers equipped with machine guns.
Only kilometres away from Bondi Beach, extra security and police were deployed for the Sydney Sixers' first home game of the BBL at the SCG on Wednesday night.
Sixers and Adelaide Strikers players wore black armbands and a moment of silence was observed before play in tribute to the victims of Australia's worst terrorist attack.
"We stand together with all Australians" was projected on the stadium's big screen, before a moment of applause honoured the first responders who risked everything on Sunday night.
Australian Test captain Pat Cummins, who was in Adelaide with the Test squad on Sunday night, lives in the eastern suburbs of Sydney.
"Like most other Aussies, I was just horrified watching on," Cummins said on match eve.
"We take the kids there all the time."
Williamson, who has described True Blue as a song for all Australians, regardless of background, sang after one minute's silence at Adelaide Oval.
After most in the crowd stood motionless, heads bowed, others started singing along.
Hey true blue, can you bear the load?
