It was reported last weekend the Rolling Stones are postponing the North American leg of their "No Filter" tour. That, of course, meant cancelling their May 2nd appearance at the New Orleans Jazz & Heritage Festival. Initial reports vaguely stated Mick Jagger needs "medical treatment." He's scheduled for a heart valve replacement this Friday. the procedure will take place in New York, according to a report from Rolling Stone. Jagger and his family were reportedly in Miami last weekend. He's expected to make a full recovery, and the Stones are expected to hit the road again this summer. By the way, Led Zeppelin is NOT reuniting to step in.That was an April Fool's joke.
