It looks like Paul McCartney's not collaborating with the surviving members of Nirvana again, after all. A report from earlier this week, citing an unnamed source at McCartney's label, has been quickly debunked by the former Beatle's spokesman.

The Macca Report, a popular fan site, initially offered the intriguing nugget as part of an anonymously sourced song-by-song preview of McCartney's still-unnamed forthcoming solo album, with other highlights including details on new tracks allegedly recorded with both Eric Clapton and Bruce Springsteen, and several previously unreleased song titles.

But no one previously knew about a second song recorded with Dave Grohl, Krist Novoselic and Pat Smear of Nirvana. McCartney had memorably performed a new original 'collaboration called 'Cut Me Some Slack" with the same trio as part of the 12-12-12 benefit concert for Sandy relief.

Not so fast, though, says Steve Marinucci of Beatles Examiner. He followed with his own story quoting a representative from McCartney's camp as saying the entire so-called leak was "bogus."

The giveaway, according to both Marinucci and Beatlefan editor Bill King? McCartney's final track in the original story's song-by-song run down was titled 'April Fool's Day.'
