McCartney, for his part, was somewhat unaware of his new bandmates' musical identities, saying:
The benefit concert will take place at Madison Square Garden, and also feature The Rolling Stones, Jon Bon Jovi, Eric Clapton, Billy Joel, and Bruce Springsteen.
I didn't really know who they were. They are saying how good it is to be back together. I said: 'Whoa? You guys haven't played together for all that time?' And somebody whispered to me: 'That's Nirvana. You're Kurt.' I couldn't believe it.
