Giants 1989 had 80,000, as well as the show in Stuttgart 1996. I have no idea about the attendances in Moscow '89, MK '89 or Donnington '87, but those were probably some of the biggest shows. I read once that 120,000 people attended the show at the Hollywood Rock festival in Rio 1990, but I'm not so sure about that. Oh, and of course, Hyde Park 2003! Officially there were about 90,000, but halfway through the show about around 120,000 saw and listened to the show.
