The Damned released I Just Can't Be Happy Today in November of 1979 and it was less of a punk single and more of a social commentary than anything else. By the end of 1979, there weren't many real punks left anyway. Everyone was well on their way to having a career or two.
What I like about this cover is the simple garishness of the images. Someone has vandalized a staid, stuffy old statue and put an absurd piece of headgear on it and they have slapped modern graphics across the front as an afterthought. I love this stuff, especially when it is well done.
