Foo Fighters offshoot band Chevy Metal was joined onstage by Foos frontman Dave Grohl, Motley Crue and Sixx: A.M. bassist Nikki Sixx and Foos drummer Taylor Hawkins' 11-year-old son during a performance this past Saturday (December 22nd) at the Los Angeles Regional Food Bank.

Chevy Metal performs covers of classic metal tracks and is led by Hawkins and bassist Wiley Hodgden. Hawkins's 11-year-old son, Oliver Shane Hawkins, sat in on drums for a cover of the Rolling Stones classic "Miss You," while Sixx joined the group for two Motley Crue classics, "Looks That Kill" and "Live Wire."

Grohl appeared with the band to cover Thin Lizzy's "Jailbreak," Black Sabbath's "The Wizard" and the Rolling Stone' "Bitch," while also joining in on "Miss You."

Hawkins told us a while back that classic rock and metal have always influenced him: "It's there, you know, and I wear 'em heavily on my sleeve, my influences. It's in my DNA now, you know. I've listened to it enough. I'm under the influence, no question, you know."

Proceeds from the performance, part of the food bank's "Eat, Drink And Support" drive, are being used to serve many meals to hungry Angelenos this holiday season.
