Nobody Knew What To Expect When This 82yo Grandpa Stepped On Stage. Seconds Later, Entire Crowd Erupted

The best thing about “America’s Got Talent” show is that you can always expect the unexpected. For example who would have ever thought that an 82-year-old former aerospace engineer and Navy pilot would have anything to do with singing?!

John Hetlinger is a man who worked on the Hubble Telescope, but now he just sings karaoke. He claims that this performance would be the highlight of his life and career! Well, I am not sure about that, but he definitely left everyone completely stunned!

Check out the 82-year-old dude singing Drowning Pool’s metal classic, “Bodies,” and prepare for your jaws to drop! It’s no wonder that he received a million views in just seven hours on the metal social media site. So, go ahead and share this “mind blowing” performance.
