Paul McCartney will fill the role of Kurt Cobain when he plays with the surviving members of Nirvana at the 12.12.12 concert for victims of Superstorm Sandy on Wednesday night.

The former Beatle will join Foo Fighters singer Dave Grohl and bassist Krist Novoselic on stage in New York to play a new song after secretly working with the pair. Grohl and Novoselic have not performed with each other for 20 years.

A spokesman confirmed that Grohl recently asked McCartney to come along to "jam with some mates".

The former Beatle suggested they "just make something up" and found himself playing with Grohl on drums, bassist Novoselic and guitarist Pat Smear, who toured with Nirvana for the last six months of the band's career.

Kurt Cobain took his own life in April 1994.

As a life long Beatles and Nirvana fan - I immediately crapped my pants after reading this news about McCartney and Nirvana.
