During the band's performance at the Monsters of Rock festival in Castle Donington, England, in August 1988, two fans were crushed to death when many in the crowd of 107,000 began slam-dancing to "It's So Easy". Rose had halted the show several times to calm the audience. From then on, he became known for personally addressing disruptive fans and giving instructions to security personnel from the stage, at times stopping concerts to deal with issues in the crowd. In 1992, Rose stated, "Most performers would go to a security person in their organization, and it would just be done very quietly. I'll confront the person, stop the song: 'Guess what: You wasted your money, you get to leave.'" As a result of the deaths at Monsters of Rock, the festival was canceled the following year.
