Nirvana.... ft Paul McCartney?

It's for charity. Good for all of the guys involved. I'm not a Beatles or Nirvana or Foo Fighters guy but I'd never turn down the chance to meet let alone play with any one of those guys.
 
I'm not overly annoyed about it, i'm just a bit wtf at the fact it's paul McCartney, there are so many people that would fit better :L

Plus the fact that I love Nirvana/absolutely despise The Beatles aided the initial rage :D
