During Helloween’s performance of “Best Time” on Friday night at the YouTube Theatre in Los Angeles, California, FOZZY vocalist and AEW star Chris Jericho joined them onstage. For those unaware, Jericho took his famous surname from the band’s 1985 album “Walls Of Jericho,” so this was likely a massive moment for him to perform with the German power metal band that was formed in 1984. A fan-filmed video of this can be viewed below.
