Music fans have turned to Change.org around the globe to try and block West's participation at various events. The largest unsuccessful petition has been to the Glastonbury Festival 2015 with 133,000+ voters stating they would prefer a rock band to headline. On July 20, 2015, within five days of West's announcement as the headlining artist of the closing ceremonies of the 2015 Pan American Games, Change.org user XYZ collected over 50,000 signatures for West's removal as headliner citing the headlining artist should be Canadian. In his Pan American Games Closing Ceremony performance, close to the end of his performance, West closed the show by tossing his faulty microphone in the air and walked off stage.
