Ever since opening his tour with the first live rendition of “A Hard Day’s Night” since 1965, Paul McCartney has been pulling out all the stops on his One on One tour. Last night at the Key Arena in Seattle, WA was no exception, as McCartney called on local legend Krist Novoselic to make a guest appearance.

The Nirvana bassist/co-founder brought his talents to the Beatles song “Helter Skelter,” rocking along quite aptly with the legendary McCartney. Check out video from the show below:

McCartney resumes his tour tomorrow night, for a two-night stand in Vancouver, BC. Check out the full setlist from the performance below:
