Illness Forces John Mayer to Cancel Concerts

Singer John Mayer has cancelled a string of recent shows due to an illness.

According to his Web site, Mayer nixed a series of European performances scheduled for this week.

"After a sold-out performance in Copenhagen, John Mayer was forced to cancel his second show there on [May 31] due to illness," a post on his official site reads, in part. "Regrettably, the illness has caused his remaining European shows scheduled through this week to be canceled as well (Amsterdam, Madrid and Manchester)."
