Watch: Guns N' Roses joined by Angus Young for AC/DC songs in Sydney, Australia

Guns N' Roses launched their Not In This Lifetime Tour of Australia on Feb. 10 in Sydney at ANZ Stadium. The legendary Los Angeles rockers dazzled the Auzzie crowd with a powerful 24-song setlist, which included a surprise guest appearance by AC/DC guitarist Angus Young for a  pair of songs.

Blabbermouth reports on Feb. 10 that the hometown hero joined the “Sweet Child O' Mine” hitmakers near the end of the night and played guitar on two AC/DC songs - “Whole Lotta Rosie” and “Riff Raff.” Young performed the same two songs with the multi-platinum once before during Guns N' Roses' initial headline performance on April 16, 2016 at Coachella.

The action was caught in a 11:27 minute fan-shot video. GNR frontman Axl Rose casually announces Young to the delight of the Sydney crowd, following the wrap up of Guns N' Roses signature song “Sweet Child O' Mine.” Young takes center stage armed with his trademark Gibson SG guitar and leads Rose and company through the two late 70s AC/DC classics. Fans can can check out both performances above.

"We're gonna bring out a friend of ours," Rose announces nonchalantly. “Ladies and gentlemen, Angus Young!"

Young made headlines earlier this week when he surprised the reunited L.A. rockers by showing up during their arrival at the airport in Sydney on Wednesday. Young and Rose became temporary bandmates when the GNR singer stood in for ailing AC/DC frontman Brian Johnson during the legendary Auzzie rockers' massive Rock Or Bust Tour in 2016.  

The Not In This Lifetime Tour will continue with the second show of a two-night stand on Feb. 11 at Sydney's ANZ Stadium. Guns N' Roses will hit New Zealand, Singapore, Thailand and United Arab Emirates before launching a spring tour of Europe, which kicks off May 27 in Dublin, Ireland, at Slane Castle.

The Rock and Roll Hall of Famers will return to North America beginning June 27 in St Louis at Edward Jones Dome At America's Center. The summer romp is slated to wrap up Sept. 8 in San Antonio, Texas, at Alamodome.
