Remember when John Hetlinger, a man who happens to be 82 years old, stunned the America’s Got Talent panel and the world at large with a bruising performance of Drowning Pool’s 2001 bruiser "Bodies”? That story dominated the blogosphere hard.

Now, Hetlinger will dominate our lives in another way: He’s actually joining Drowning Pool at an upcoming show. The hard rock group has asked the grandfather to perform at the Open Air Music Festival in Chicago this Friday.

Watch Hetlinger's TMZ announcement:

Drowning Pool guitarist C.J. Pierce hinted at the onstage collaboration when he spoke to Fuse last month:

“If we’re gonna do it, we might as well make it a big show. And Open Air festival is a big show coming up in Chicago next month, so that gives us time to get stuff together. But I hope it works out, I hope he does it. Live on stage with us playing, that would be so killer!”
