As concert promoter Bill Graham had given me all access to any of the concerts he produced, I spent quite a bit of time backstage with the bands, their roadies and their women.  What fascinated me were the lengths to which the women, the groupies, went to prepare themselves for their backstage appearances.  Because I also wanted an excuse to photograph them, I suggested to Jann that they might make an interesting story.  He agreed and Issue No. 27 became known as “the groupie issue.”  It was widely promoted, read and commented upon, even turned into a book.
