Foo Fighters perform 'Molly's Lips' in concert

It's the first time the band has ever performed the song, even though Dave Grohl famously performed it with Kurt Cobain and Nirvana in 1991.

According to Spin.com, Pat Smear started playing the song's riff, and the rest of the band joined in, performing the entire track.
