The Rolling Stones postponed their tour so that Mick Jagger can have heart valve replacement surgery, The Sun and Rolling Stone reported. The 75-year-old rocker is set to have the procedure Friday in New York City and could be out of the hospital in 48 hours, according to the reports. The band announced this weekend that it was putting a hold on the North American leg of its tour for an unspecified “medical treatment” for Jagger. “I really hate letting you down like this. I’m devastated for having to postpone the tour but I will be working very hard to be back on stage as soon as I can,” Jagger said in a statement.
