WATCH: Axl Rose Joins Billy Joel On Stage For 'Highway To Hell'

The unlikely pairing of Axl Rose and Billy Joel happened again!

On Friday night, the Guns N’ Roses frontman joined Joel on stage during the latter’s concert in Minneapolis for a cover of AC/DC’s 1979 classic “Highway to Hell.”

Rose, 55, also made a surprise appearance at Joel’s concert in L.A. back in May.

The 68-year-old Piano Man often performs “Highway to Hell” at his shows — with his roadie handling lead vocals.

Rose was able to drop by because GnR were in Minneapolis for a show on Sunday night.
