This is incredibly unfair, I know, but here's what you need to know about this photo.
First, it's of the band All About Eve.
Second, it's a promotional photo so everyone has been styled, dressed, and made up. Their record label probably spent a large sum of money on this photo.
Third, these are not miserable people, but they are posed in such a way as to appear miserable. When the man said, "no mardy bums," this was what he was talking about. But All About Eve were excellent and talented so it all worked out in the end.
Fourth, whoever took the photo did the band a disservice and should have opted for something else. As in, anything else.
When there actually were record labels and photographers who did this sort of thing, the promotional photos were used to help the A&R people "sell" the band. Not much of that happens anymore. But, if you're in a band and if the person trying to take your picture does this to you, beat them up.
