Neil Young Performs With Steven Stills; The Heartbreakers Reunite For First Performance Since Tom Petty’s Death: Watch

The Light Up The Blues benefit concert for Autism Speaks was more than eventful.

When Stephen Stills graced the Dolby Theater auditorium, it came as a surprise considering the two artists’ complicated relationship recently regarding the future of Crosby, Stills, Nash & Young.

Regardless, their musical chemistry shined as they performed “Long May You Run,” along with the The Buffalo Springfieldanthems “For What It’s Worth” and “Mr. Soul.” They were later joined by Patti Smith for an inspiring performance of “People Have The Power.”

Stills, who organized the benefit concert alongside his wife Kristen in support of their autistic son Henry, addressed the Los Angeles crowd at one point saying, “With the help of steadfast friends and concerned professionals that shared our determination, Kristin and I…were able to find a path that lead our boy to a far better way of life, and now he’s in college.”

An even grander surprise rocked the house during last night’s performance. The Heartbreakers, who haven’t performed since Tom Petty’s sudden death this past October, took the stage to perform the rocking “I Won’t Back Down” alongside Stills. Patti Smith also returned to the stage to perform “Because The Night,” while Beck unexpectedly joined the band to perform a powerfully haunting rendition of “Guess I’m Doing Fine.” Beck also performed his own track “Where It’s At.”

While no announcement has been made regarding The Heartbreakers status as a band, it was announced at the beginning of April that guitarist Mike Campbell will join Fleetwood Mac on tour alongside Crowded House vocalist Neil Finn in the wake of Lindsey Buckingham’s sudden firing. “We are thrilled to welcome the musical talents of the caliber of Mike Campbell and Neil Finn into the Mac family,” read a statement issued by Fleetwood Mac to Rolling Stone. “Fleetwood Mac has always been a creative evolution. We look forward to honoring that spirit on this upcoming tour.” Other performers throughout the night included Sheryl CrowJudy Collins and Burt Bacharach.
