Those About To Rock (We Salute You) is one of AC/DC's more memorable songs.
But it's music lovers worldwide who are now saluting AC/DC guitarist Malcolm Young, who died on Saturday after a period of ill health in Sydney at the age of 64.
Malcolm Young made his name as guitarist and songwriter with the seminal Australian rock group. He founded the group in 1973 with his younger brother Angus.
It became what is arguably the nation's greatest ever musical export and is still one of the biggest acts in the world.
But in December 2014, he revealed he had dementia which forced him to retire.
Angus Young later revealed that he realised during the recording of the 2008 album, Black Ice, that his brother's faculties were impaired.
Malcolm had been diagnosed with lung cancer that year. He received early treatment, but his health problems continued when doctors discovered he had a heart condition that required a pacemaker. Then dementia struck.
"It was like everything hit him at once," Angus Young said.
"The physical side of him, he got great treatment for all that so he's good with all that, but the mental side has deteriorated. He himself has said, `I won't be able to do it any more'."
Young took a leave of absence from the band in April 2014, and in September announced his retirement.
He urged the band to continue touring and making music. Steve Young, his nephew, replaced Malcolm in the line-up for AC/DC's next album, Rock Or Bust.
