On May 25th, Trixter guitarist Steve Brown hit the stage with Def Leppard in Hershey, PA in place of Phil Collen, who left the band's current tour with Journey due to a family emergency. Fan-filmed video of Brown performing with Def Leppard is available below. No word yet as to when Collen will return to the fold.

Brown previously performed with Def Leppard back in 2014, stepping in when Vivian Campbell was undergoing treatment for Hodgkin's lymphoma.

Def Leppard and Journey launched their co-headlining North American tour on Sunday, May 21st at XL Centre in Hartford, CT. In this new video from Associated Press, Def Leppard's Joe Elliott and Journey's Neal Schon discuss the trek.
