Singer Kevin Sharp has been released from the hospital following hip surgery and has already resumed fulfilling his concert schedule. He flew into California on Tuesday, June 23rd for the needed surgery that he was putting on hold until later in the year. The "Nobody Knows" singer was forced to cancel his Fan Fair activities after collapsing backstage during Monday's TNN Music City News Country Awards. Sharp had experienced problems with the steel rods that had been placed in his hip during cancer treatment seven years ago.
