John Hetlinger, the 82-year-old contestant who sang Drowning Pool's song Bodies " on America's Got Talent, was invited by the band to sing the song live at Chicago Open Air.
In an interview with KUSA, Hetlinger commented on his success:
“I didn’t know that 2,500 people in the audience would react the same way 30 drunks in a bar react, but they did! Everyone seems to think it’s great that an old man is singing ‘let the bodies fall to the ground!’”
