The show must, and did, go on Sunday night (July 22) in Toronto when production issues resulted in Hayley Kiyoko missing her opening slot on the Panic! at the Disco Pray for the Wicked tour. According to an Instagram post from Kiyoko, when her band's set at the Air Canada Centre was scotched due to "border/production delays" Panic! singer Brendon Urie invited her out to perform "Girls/Girls/Boys" and it totally made her night.    

"I cannot tell you how incredible this man is," she wrote in the caption to the clip where the pair enthusiastically sing the pop number while draped in rainbow flags. "Not only is his voice a gift but his KINDNESS and ability to make people feel warm and special is just beyond. Thank you Brendon for giving me something to aspire to and be. And supporting me as if we are family. I’ll never forget last night."
