Following Saturday night's horrible stage collapse tragedy at the Indiana State Fair, Sugarland have cancelled their Sunday (August 14) performance at the Iowa State Fair. According to a statement on the fair's website, the concert will not be rescheduled but fans will be able to collect a refund for their tickets.

"Aside from coping with the magnitude of the accident, the ongoing investigation prevents the band from getting what may remain of their stage equipment," the statement reads. The Sugarland duo was understandably shaken by last night's events, which resulted in over 40 injuries and the death of five people.

Sixty mile-per-hour winds blew the Hoosier Lottery Grandstand stage on top of the awaiting crowd just before 9:00PM, only a few minutes before Jennifer Nettles and Kristian Bush were expected to take the stage. Opening act Sara Bareilles had concluded her performance just a half hour earlier.

Fans who wish to return their tickets to tonight's cancelled Sugarland/Sara Bareilles show must do so at the point of purchase in order to obtain a refund. Though there are no current plans to reroute the Incredible Machine Tour back to Des Moines, the fair site says that the fireworks display which usually runs following concerts will still go off at 10PM tonight in honor of the victims in Indiana. Additionally, the Iowa State Fair will hold a moment of silence on the morning of August 15.
