(FILES) Canadian singer Celine Dion performs on the opening night of her new world tour "Courage" at the Videotron Centre in Quebec City, Quebec, on September 18, 2019. Paris has come down with a serious case of Celine Dion fever ahead of the 58-year-old's first full concert on Saturday since revealing she was suffering from a rare neurological disorder that forced her off stage. Those who missed out on tickets for the French-Canadian chanteuse's 26 upcoming shows are finding other ways to join the frenzy -- including giant karaoke parties where fans can sing their hearts out, even if they won't get to see their idol in person.
