Last time Judas Priest went to see a tribute band, they ended up with a new singer. This time, though, they gave fans expecting to see a tribute show more than they bargained for.

After headlining their own show at the Spektrum in Oslo, Norway Wednesday night (June 14), Priest’s Glenn Tipton, Richie Faulkner and Scott Travis went to see a Norwegian tribute group called Painkiller at the Hard Rock Café. The three then joined Painkiller onstage for a rendition of “Metal Gods.” You can watch video of the performance up top.
