After postponing a week's worth of concerts last week, Van Halen has decided it needs to hold off their reunion tour for the next month while Eddie Van Halen receives "medical tests" for an unspecified problem. The tour has now been put on hold until April 19th, leaving seventeen postponed dates — including a show at New York City's Madison Square Garden — in limbo. No rescheduled dates have been announced, but fans are being asked to hold onto their tickets for use on a later date. According to organizers, Eddie Van Halen "is currently under doctors' care" and will "continue medical tests to define a course of treatment." The tour is, as of now, expected to resume with an April 19th show in Las Vegas.
