BOSTON (AP) — Keith Moon, drummer for the English rock group "Who," collapsed on stage at the start of a concert at Boston Garden Tuesday night, promoter Don Law said.

The collapse was due to viral influenza, Law said, and Moon was under the care of doctors at his hotel.

Law said the concert would be rescheduled for April 1 and ticketholders for Tuesday's concert should watch local newspapers for ticket-honoring instructions.
