Australia rugby player Sam Talakai made his debut against Wales in Cardiff, and treated the post-match audience to a rousing rendition of Livin' On A Prayer by Bon Jovi.
Last weekend, Wayne Pivac's side conceded 26 unanswered points to the Wallabies, resulting in a momentous defeat for Wales. Dave Rennie's Australia will have been bouncing off the walls after the dramatic ending, and that energy transferred into Talakai when he took to the microphone to sing the iconic 1986 smash hit after the match.
According to former Wallaby Drew Mitchell, who was capped 71 times for his country, it is a Welsh tradition that is performed by newly-capped players once they have been presented with their first cap.
