Speaking on an Australian TV documentary called On The Brink: Bon Scott, brother Derek says Bon “never worried about tomorrow”.

The family of Scots rocker Bon Scott tried to stop his drinking before his tragic death from alcohol poisoning, a TV documentary reveals.

But their efforts to save the AC/DC frontman failed as he wouldn’t quit booze, according to his younger brother Derek.

The singer’s sibling reveals their mother, Isa, called out Bon’s heavy drinking before his death, at the age of 33, from acute alcohol poisoning in 1980.

In Australian TV documentary On The Brink: Bon Scott, Derek says Bon “never worried about tomorrow”.

He added: “My mother always told him, ‘You’re drinking too much.’ But you could only say it once, maybe twice. After that, he argued.”

Bruce Howe says he saw his pal Bon’s personality darken in the months before his death.

The pair, who played together in the rock band Fraternity before Bon joined AC/DC in 1974, crossed paths for the final time in late 1979.

Bruce said: “He wasn’t bubbly and laughing. Maybe he’d come to the state where he’d achieved his dream and found his holy grail but found it might have looked like an empty goblet.”

Bon was born in Forfar and raised in Kirriemuir, Angus, before his family moved to Australia when he was six.

AC/DC, who also featured Glasgow-born brothers Angus and Malcolm Young, became one of the biggest-selling bands of all time.
