During a recent Japanese interview, Dave Grohl touched on an interesting topic - do fans prefer Nirvana or the Foos - saying (via Alternative Nation):
"It's funny, there are times where I'll meet people, they know about the Foo Fighters, but they don't realize I was in Nirvana.
"But then also, our audience has been around for so long that now parents bring their kids to shows.
"You would imagine it would be the parents with the Nirvana shirts and the kids with the Foo Fighters, but it's actually the opposite.
"The parents are wearing Foo shirts, and the kids are wearing Nirvana shirts. Nirvana is like classic rock now to some people."
