The song, which is sung by three goonies going to a party. This pop melody later merges organically with the composition next in the soundtrack – Girls Just Want to Have Fun. This is a kind of male version of the female song of a carefree singing. First and second are telling of the fact that some people go to some party, to dance and to spend their money, which is not clear where they get it as if they are idle crowd.
