The lead on this article suggests Studio 54 and Saturday Night Fever happened in the 80's... both peaked in the 70's. (1977 for SNF and by 1980 S54 was becoming a memory) Both have styles that are distinctly different from anything 80's.  In fact, by 1980 the term 'Disco is Dead' had worked its way into the national lexicon.  Please put a little more effort into these introductions!  Thanks.
