Sept. 1, 1989 – Pittsburgh, PA
The Hooters opened for Stevie. The arena top was supposed to open that night but because of weather it was closed. The Pittsburgh Press wrote an article the next day and asked the question why Stevie Nicks moved so little during her concert. Her reps stated it was because she recently broke her foot and was favouring the foot by not moving. Some fans recall seeing Stevie wearing a cast painted black on her leg. She had supposedly slipped and fell in a swimming pool. Rumours swirled that she had not really broken her foot but that her reps were covering for her Klonopin years. Also this was originally supposed to be the tour’s opening date but for some reason the dates were changed and the tour opened in Detroit instead. Fans recall this being the only Stevie or Mac show since the mid-seventies where Rhiannon was not played. And finally, it was at this show that a male fan jumped onstage during ‘Has Anyone Ever Written Anything For You’, and hugged her. She kept singing and said ‘I am not afraid’ as security dragged him off
