Krist Novoselic has joined his former Nirvana bandmate Dave Grohl's band Foo Fighters before, and he did it again last night (9/1) at Seattle's Safeco Field, this time to cover The Vaselines' "Molly's Lips," which Nirvana had a well-known cover of (included on their 1992 compilation Incesticide. The band, whose lineup also includes Nirvana live member (and Germs co-founder) Pat Smear, did the song in the same punked-up way that Nirvana did back in the day, and they sounded great. Check out a video below.

Krist Novoselic was in the house because his band Giants in the Trees were opening the show. They're also playing the Foo Fighters' Cal Jam '18 in October.
