Paul McCartney's One on One Tour has been packed with surprises since its Fresno launch on April 13th, with the singer performing tracks like the Beatles' "A Hard Day's Night" and "Love Me Do" for the first time as a solo artist. McCartney's Seattle stop Sunday also featured an unexpected change in the setlist as Nirvana bassist Krist Novoselic came onstage during the encore to perform "Helter Skelter" with his one-time "Cut Me Some Slack" bandmate.
McCartney and Novoselic previously performed together – along with Dave Grohl and Pat Smear in an outfit playfully dubbed "Sirvana"– at the 12.12.12 benefit, a December 2012 episode of Saturday Night Live and a July 2013 McCartney concert at Seattle's Safeco Park. In a recent Rolling Stone interview, Novoselic discussed the prospect of further collaborating with McCartney as well as his former Nirvana bandmates.
"These things come up," Novoselic said. "It's always fun. We'll see if there's anything in the future. I don't know. I haven't heard of anything."
McCartney's One on One tour continues Tuesday and Wednesday with a pair of shows in Vancouver, British Columbia.
