John Mayer has cancelled the rest of his European tour dates, all which were sold out, and a festival.
It is undisclosed what John has but his next tour date in North Carolina July 16th has not been cancelled so he might be back on the road in about a month or so.

"Regrettably, the illness has caused his remaining European shows scheduled through this week to be canceled as well (Amsterdam, Madrid and Manchester). Ticket holders should apply for refund from point of purchase. Mayer is returning home to the States, and a full recovery is expected under a doctor's supervision."
We wish John a speedy recovery and hope he is feeling better soon.-Dr.FB
