VIDEO: Classic Rock Giants Come Out For Stephen Stills’ Autism Speaks Benefit Concert

There's nothing like rocking for a good cause, and some of classic rock's biggest names came out to take part in Stephen Stills' "Light Up the Blues" benefit concert for Autism Speaks.

There were many highlights of the night, but perhaps the biggest came when The Heartbreakers' Benmont Tench, Mike Campbell and Steve Ferrone took to the stage for the first time together since the passing of Tom Petty and performed "I Won't Back Down" with Stills on vocals.

Stills and Young also shared a memorable moment on stage playing The Stills-Young Band's "Long May You Run," Buffalo Springfield's "For What It's Worth" and "Mr. Soul."
