Johnny Hallyday, one of France’s biggest rock stars, has canceled the final part of a concert tour, according to the AP. The 66-year-old singer was hospitalized last week in Los Angeles following complications from a back operation that was performed last month. Doctors awakened Hallyday Tuesday after the singer spent several days in a medically induced coma. Hallyday was scheduled to tour France with performances in January and February, but those shows have since been canceled, and ticketholders will be reimbursed.
