This weekend at Rock In Rio Weezer was taking the stage and decided to do a Nirvana cover. Rivers was a self-proclaimed “biggest Nirvana fan.” Dave Grohl was backstage cause Foo Fighters were about to go on and heard Weezer’s cover of “Lithium.” Grohl said he cried a little bit cause he loved playing that song. Check out the Weezer cover and Dave Grohl’s reaction below!
