They are coming and are going to donate their time and talents, is about what it amounts to," said state fair spokesman Andy Klotz.Fieldhouse employees and stagehands are also volunteering to work at the event.Maroon 5 and Train fans said they're proud of the bands for supporting Hoosiers in their time of need and glad the money will be donated to the victims' fund."It really shows how, you know, just how the community can come together after a tragedy," said Tiffany Tran."I was surprised at first (that the money would be donated), but then I was really glad," said Jarden Wooten.Train lead singer Pat Monahan offered his condolences in a statement Monday."I am so sad for these people that were injured or worse by this absolutely awful collapse, and I am thinking of you all constantly and sending love," he said.

"Is there anything that could have been done? I don't know the answers to those things, but somebody does."Additional tickets have been opened up for Thursday's show. PJ Morton will open the concert, which begins at 7 p.m.More information about seating and tickets can be found on the state fair's website.
