A few weeks ago, Weezer paid homage to indie-pop newcomers Foster The People by performing a cover of “Pumped Up Kicks” during a show at the Orange County Fair. At Outside Lands 2011, Foster The People decided to return the favor by performing the alt-rock classic “Say It Ain’t So”–much to the delight of festival goers. Thanks to powers of YouTube, we have video of this festival highlight just hours after the show. Check it out!
