Bruce Springsteen and the E Street Band welcomed Pearl Jam frontman Eddie Vedder to the stage for a pair of songs on Saturday (Feb. 15) in Melbourne, Australia. The Boss and the PJ singer duetted on both AC/DC's "Highway To Hell" and Springsteen's "Darkness on the Edge of Town."

"We're going to have some help opening the show tonight. Let me bring up Eddie Vedder!," Springsteen announced to the massive crowd at Melbourne's AAMI Park. The show then kicked off with the Boss and Vedder sharing vocals on AC/DC's rocker "Highway To Hell." Next, Springsteen performed his classic "Darkness on the Edge of Town," with the Pearl Jam frontman again singing with him.

Guitarist Tom Morello shared a post-show photo on Instagram of himself, Vedder and Springsteen with the caption, "Vedder/Springsteen/Morello trifecta bask in afterglow of Melbourne #1. Ed slayed Highway To Hell/Darkness On The Edge Of Town."

Springsteen's Melbourne gig on Saturday is part of his current Australian tour in support of new album "High Hopes," which debuted at No. 1 on the Billboard 200 earlier this year. Vedder also happened to be down under because he's currently in the midst on a solo tour of Australia following Pearl Jam's recent run headlining the Big Day Out Festival.

Vedder's guest appearance at Springsteen's show Saturday was not his first time onstage with the Boss. The PJ frontman previously performed with Springsteen a handful of times, including joining the Boss onstage at Chicago's Wrigley Field in September of 2012, at a pair of 2004 concerts in New Jersey and Washington DC, and at a 2002 Chicago Springsteen show. In 2009, Vedder performed for Springsteen at the Kennedy Center Honors Springsteen gala.

Bruce Springsteen and the E Street Band will follow its current run of dates in Australasia with an American Tour that kicks off April 8 in Cincinnati and runs through May 18 with a date in Connecticut. Pearl Jam is next set to hit the road for a European tour that begins June 16 in Amsterdam and wraps July 11 with a U.K. date.
