The theme of this video seems to be that Def Leppard is the band that has fun onstage and off!
This footage for this video was shot over the course of two shows at McNichols Arena in Denver, Colorado. Originally, the footage was going to be used for a future concert film but, when Armageddon It was released as a single, the band’s record label said that they needed a music video to accompany it and they needed it immediately. Since the band didn’t want to do another “concept video” (and really didn’t have time to come up with a concept in the first place), the Denver footage was hastily edited together.
The end result was that Armageddon It went on to the become the band’s fourth top ten hit in the United States.
