KALAMAZOO, MI -- Miller Auditorium has been unable to reschedule a May 20 concert with Willie Nelson that was postponed because of illness.

Tracey Lawie, director of marketing for Miller, said, "We just haven't been able to find a date that works for both schedules. As opposed to continuing to hold people's money, we're offering refunds at this point."

She said they continue to work on finding a new date for a concert with the country music legend.

Refunds are available at the Miller Auditorium box office or by calling 800-228-9858.
