Could be Dave's way back strategy.
*If* they were going to tour it...who would you want up front? "I don't want them to tour" is not a valid answer to *this* question.
Joan Jett was the pick the other night - thought St Vincent was all over the shop, which was odd. John MacAuley of Deer Tick has been the best of who they've had so far, so he'd probably be my pick, though I think Dave would pick a female vocalist, which is fair do's. But who?
Any gender...
that's exactly how I felt about it until I went to the Rock and Roll Hall of Fame performance. As someone who never got to see Nirvana, I found it incredibly emotional to witness them play live, each song with a female vocalist of a different generation. I don't think it's a show that needs to tour, but I love that some formation of the band happens from time to time. It's like a getting one more hug from a friend that's passed away.
