NORMAN, Okla. - Thousands packed into Gaylord Stadium to enjoy the Oklahoma Twister Relief Concert.
Saturday night was full of emotion and special meaning, especially to Moore native and country superstar Toby Keith. For him, this was the performance of a lifetime.
The concert was inspired after he walked the streets of his hometown after the May 20 tornado.
"You have to walk through to really see stuff with your own eyes before you can tell how much shrapnel had to be in the air to do that much damage and flying that fast." Keith said. "It's probably exactly what a war-zone looks like."
Unfortunately, the severe summer heat turned into a big problem as the music got underway.
Paramedics treated 150 people for heat-related illnesses, 16 people went to the hospital, three of them were in critical condition.
Medical experts said alcohol could have been a factor for some of the injuries.
"Now at this venue they're serving beer so any alcohol will dehydrate you so you need to drink even more water," Deputy Chief Jim Bailey said.
All the money raised from the concert will be given to The United Way of Central Oklahoma May Tornadoes Relief Fund.
