Paul McCartney’s 39-song show at the Key Arena in Seattle last night was highlighted by a special collaboration with Nirvana bassist Krist Novoselic, who joined Sir Paul late in the show for a cover of the Beatles’ “Helter Skelter” before the Abbey Road medley closed the show.

McCartney and Novoselic have a recent history together, as they were part of a project for Dave Grohl’s Sound City film that saw McCartney front Grohl, Novoselic and Pat Smear as the surviving members of Nirvana

McCartney’s One on One Tour will continue April 19 in Vancouver.
