The Foo Fighters pay tribute to Aussie rock legends AC/DC with raunchy throwback song during Perth concert

The Foo Fighters are currently on their first national tour Down Under since 2018.

And the famous American musicians have delighted their Australian fans by including a raunchy throwback song called 'Big Balls' in their setlist in tribute to local rock heroes AC/DC.

But instead of the song being sung by frontman Dave Grohl, 54, the lead vocals for the cheeky tune are sung by a member of the Foo Fighters road crew, Australian guitar tech Fiona Owen.

A fan video loaded onto YouTube, recorded at the Foo Fighters Perth concert last week, shows the small and heavily tattooed Owen, in black shorts and shirt, belting out the song's punchy lyrics.

Foo Fighters have included Owens and the song in their act for their Australian stadium tour to pay tribute to their musical heroes AC/DC reports The Daily Telegraph.

Originally recorded in 1976 by AC/DC for their album Dirty Deeds Done Dirt Cheap, Big Balls is infamous for its naughty lyrics that play on a popular slang term for part of the male anatomy.

Formed in Sydney in 1973, AC/DC became one of Australia's most successful bands of all time, selling an estimated 200 million albums in a career that spanned 50 years.

Meanwhile, Dave Grohl charmed his local fans on Friday when he took a timeout to volunteer for Melbourne's The Big Umbrella, a street kitchen charity for the homeless.

The famous 54-year-old hitmaker was spotted serving up food and spreading some Christmas cheer in the kitchen at Federation Square.

Grohl worked long hours on the food line before leaving for the Foo Fighters' next show in Sydney.

It was a particularly impressive effort from Grohl, considering it came after Foo Fighters had just wrapped up packed shows at Melbourne's AAMI Park on Monday and Wednesday.

According to the official website, The Big Umbrella, founded in 2010, was created to support the homeless and 'food insecure' people.

It is now recognized as an emergency food response organization that “supports communities affected by bushfires, floods, earthquakes, storms and pandemics,” its website explains.

The organization shared multiple images of Dave helping in the kitchen, calling him a “great volunteer.”

Meanwhile, the Foo Fighters arrived Down Under last week ahead of their first national tour of the country since 2018.

The rock band had to cancel their 2022 tour of Australia following the sudden death of their drummer Taylor Hawkins.

The rocker died suddenly in March last year at the age of 50 in his hotel room, just hours before Foo Fighters were to perform at a festival in Colombia.

Foo Fighters kicked off their Australian stadium shows in Perth on November 29 and have already completed their scheduled dates in Adelaide, Melbourne and Sydney.

Their next show is December 12 in Brisbane.
