Brendon Urie, vocalist of Panic! At The Disco, was unable to perform with the band on Saturday in Salt Lake City, Utah due to having a fever of 102, and potentially becoming ill with malaria (tests for malaria later came back negative).
Instead of cancelling the show, the band decided to gather guest vocalists to help perform a full set. Dallon Weekes (the band's live bassist), Tyler Glenn of Neon Trees, Ransom of King Niko, and Ash of Exit Strategy all helped the band perform.
