Aerosmith fans will probably be blue instead of green this St. Patrick's Day. The concert, scheduled for Friday at Breslin Center, has been canceled after frontman Steven Tyler became ill — and it doesn't look like it will be rescheduled any time soon, said Scott Breckner, director of Breslin Center. "We've just been told it's related to his voice," Breckner said.

More than 8,000 tickets were sold for the concert, with Cheap Trick also set to perform. Breslin Center officials are notifying people through the Internet and by phone, but it's hard to track people who bought tickets with checks or cash, Breckner said.

The tickets will be refunded in full. Credit cards will be automatically credited and those who purchased tickets with cash or check should go where they bought the tickets for a refund.
