Things got loud this morning at the All-American Summer Concert Series, with rock legends Twisted Sister thrilling their diehard fans with an epic performance. It was easily the biggest crowd of the summer outside the Fox News headquarters.

Watch above as Dee Snider and Co. perform the classic 1980s metal anthem, "We're Not Gonna Take It."

After hearing "I Wanna Rock," earlier in the show, even Geraldo Rivera was moved to head-bang on the curvy couch!

Check out the rest of this summer's scheduled performers! 

Earlier on Fox and Friends, Snider talked to Brian Kilmeade about the original five members of the band getting back together after a 15-year hiatus.

Guitarist Jay Jay French also highlighted a great cause that he is promoting. French introduced an eye doctor who he said saved his daughter from blindness.

French's daughter, Samantha, suffers from a rare eye disease called Uveitis. The band will perform at a benefit concert Sept. 5 in an effort to raise awareness and help the work for a cure.
