'On Saturday night, Weezer were playing the main stage at Brazil’sRock in Rioright before Foo Fighters’ headlining set. Near the end of their show, Cuomo told the crowd, “We’re gonna cover a song from Dave Grohl’s old band to tide you over until the main course in a few minutes.” They then went into an appropriately crunchy rendition of theNevermindcut.
When Foo Fighters took the stage later on, Grohl acknowledged Weezer’s cover by dedicating “Big Me” to their fellow rockers. “Tonight I’m gonna dedicate this one to Weezer,” he said, strumming the opening chords of the song. “I was backstage and I heard Weezer play the ‘Lithium’ song. I gotta be honest, I cried a little bit. I did! I miss playing that song. I miss it, so I’m happy to hear Weezer play it again. So this one goes out to the sweet Weezer.”' - via COS
