Will Paul McCartney Sing for Nirvana Tonight?

There are reports that Paul McCartney will front a Nirvana reunion with Dave Grohl and Krist Novoselic at tonight’s 12-12-12 Hurricane Sandy Relief Benefit, with Sir Paul standing in for the late Kurt Cobain.Though they are not expected to perform such delightful Nirvana classics as “Dumb” or “Lithium”, the performance may have fans clamoring for more — and we wonder if that could lead to a brand new album.
