He's probably talking about Page's performance on the Julie Felix Show.

It's definitely from Denmark. I remember seeing it in an Danish article some time ago (and which I've lost the pdf of ) where the story behind it was described briefly. The author further wrote about the first Scandinavian tour and (iirc) how he had some trouble finding material for some article that he had to write at the time. This led to that he went to the Gothenburg gig some days later. It might have been him/his photographer who took the photos that were used for the portrait collage, where they all look so pissed off.
