McCartney has canceled his concert in South Korea next week due to the virus-caused illness that forced him to call off his entire Japan tour, organizers said Wednesday, May 21, 2014. The former Beatle, who turns 72 next month, had planned to hold concerts in Japan and South Korea as part of his world tour. (Photo by Zach Cordner/Invision/AP, File)
