I agree, Nancy... Fleetwood Mac
definitely needs to make an appearance on The Late Show, and for all the reasons everyone else cited.
Perhaps they will, when the tour winds back to New York... though I've also wondered if there was some kind of exclusivity deal with NBC, to get them on Dateline, the Today Show, and the Tonight Show.
Those kinds of deals only cover a certain period of time though, so hopefully nothing would prevent them from visiting their old pal, Dave.
Warner Bros. might even be ready to release a third single by the time they'd be appearing... so hopefully we'd get to see them perform something other than "Peacekeeper" or "Say You Will."
