PHILADELPHIA, Pennsylvania: Donald Trump had promised to bring showbiz pizzazz to the Republican convention, but it was instead the Democrats who put on a slick show of A-list entertainers in their bid to elect Hillary Clinton. Shortly before Clinton’s high-stakes speech to accept the presidential nomination on Thursday (Friday in Manila), the Democratic National Convention in Philadelphia brought out one of the biggest stars there is—Katy Perry. The 31-year-old pop singer briefly gave the arena the aura of one of her shows, with delegates dancing with their illuminated phones in the air. Clutching a microphone decked out in a sparkling US flag, Perry sang two songs that Clinton could easily take as anthems—her hit “Roar” and her latest single “Rise.” Perry’s voice returned at the end of the convention as Clinton and her running mate Tim Kaine came out to her blockbuster song “Firework,” as real fireworks erupted from the stage at a packed Philadelphia sports arena. Perry, noting that her own parents supported Trump’s Republican Party, urged young Americans to vote on Nov. 8.
