“Kelly is a great performer and showman, and we may have seen the last of R&B performers like him,” Sirius programmer Geronimo said. “He’s all about the live thing. This tour is definitely one of the biggest events of the year. And the other side of it is, with his legal problems, who knows when he’ll tour again?” The singer could be facing arrest if he doesn’t show up for a court appearance today that’s related to the child pornography charges.

Kelly missed a hearing Wednesday in Chicago after his tour bus was stopped by Utah State Police. After Kelly didn’t show, Cook County prosecutors asked Judge Vincent Gaughan to issue a warrant for his arrest, saying the court had been generous in allowing Kelly to embark on his tour. The judge entered the warrant, but put it on hold until this morning, when he ordered Kelly to appear in court. It was unclear Wednesday if the outcome of the court appearance would affect the Detroit show.

A Minneapolis show scheduled for tonight was canceled, but the Joe Louis Arena appearance was still listed as “on sale” at Ticketmaster.
