As expected, Angus Young of AC/DC joined Guns n' Roses on stage in Sydney, Australia today (Friday).
Young came out about two-thirds of the way into the show and led the band through two Bon Scott-era classics -- "Whole Lotta Rosie" and "Riff Raff." Perhaps the most surprising thing about the appearance is that Young didn't appear in his usual schoolboy stage get-up. Instead he wore a white T-shirt and jeans as he soloed throughout both songs. Video below.
This was Young's second appearance with GNR within a year. The first was at Coachella in April 2016 when Axl Rose was announced as the touring replacement for Brian Johnson.
