Bon Jovi cancelled a concert in Pittsburgh midway through his performance, complaining that he had a sore throat. Jovi and his band were performing at the PPG Paints arena, and Jovi explained to the crowd that he has had a cold since Saturday. He tried to keep performing, and even joked, ?This is the day when I need a karaoke singer. Which one of you guys in a bar band knows all the words to Bon Jovi songs.? The show was meant to be two and half hours, but he had to end the show at 90 minutes.
