Footage has emerged of Aussie singer Shannon Noll barking insults at a fan in the crowd, threatening the fan and goading others to do the same.
The former Australian Idol runner-up unleashed the expletive-laden rant after a beer can was tossed on stage at the racetrack on Saturday night.
"Whoever threw that, come up here," he said to the crowd.
"Come on then, that f***head in the tie. You're a f***ing maggot. Have some f***ing balls to come up here ... cheapshot prick.
"Shame that motherf***er right there. F***ing private school stupid f***head motherf***er. Have some balls and get up here and I'll punch your f***ing teeth down your throat ... then I'll f*** your missus and your mum.
