Paul McCartney replacing Kurt Cobain in reformed Nirvana

Nirvana are set to reunite today, and the speculation is in that they’ll be getting by with a little help from their friends. Paul McCartney will be subbing in for Kurt Cobain when the grunge rockers take the stage at tonight’s concert for Sandy Relief in Madison Square Garden. Featuring other classic rock acts like Bon Jovi, Eric Clapton, Billy Joel, The Rolling Stones, Eddie Vedder and the Who, the show kicks off at 7:30pm American EST. [Stream the concert live here]
