Marcy and Siobhan, aka. Marcella Levy/Detroit and Siobhan Fahey, Shakespear's Sister, said that their idea for "Stay" was to be about 'two cat women on the Moon. ' An Earthling ends up on the Moon and Marcy falls in love with him and wants him to stay with her. That is what Marcy and Siobhan said but before I heard the interview I thought it was about Marcella's boyfriend dying and she wants him to stay with her and not go anywhere without her and that Siobhan was portraying Death and that Marcella fought Death for her boyfriend to live, either way, great song, great band, what a shame Shakespear's Sister kind of self-destructed.
