AllBum.Art - Alternative Art-Work for Album and Single Covers

There is a puzzle to be solved here. Girl Thing claim that there should be a Last One Standing, but on the original cover artwork of their single, two are squatting down and three are jumping in the air. None of them are standing, not even a last one. On the remix we find a lone babe standing on her own. She is definitely the last one standing. The new question, is where have all the others gone? Vanished!
