Guitarist is undergoing medical tests

Reunited rockers Van Halen have had to postpone four US shows as guitarist Eddie Van Halen undergoes “a battery of medical tests” according to a press statement.

Van Halen reformed last year, fronted for the first time in 25 years by original singer David Lee Roth.

The original 25-date US tour which was meant to begin last March was delayed until September whilst Eddie Van Halen was treated in a rehab centre for his ongoing battle with alcoholism.

The guitarist has also previously had oral cancer and a hip replacement.

The affected shows were due to take place this week in Dallas, Cincinnati, Baltimore and Raleigh.

They are expected to be rescheduled to take place next month.
