I'm partly confused by this debate between BN and FM.
Since Christine left, Fleetwood Mac is Lindsey/Stevie with John/Mick as the rhythm section. The only difference in a new Buckingham/Nicks album/tour vs a Fleetwood Mac album/tour is no involvement from Mick and John. Obviously a new BN album/tour would still need a drummer and bass player. Does anyone here know of anybody better than Mick Fleetwood and John McVie?
It would be almost rude of Stevie and Lindsey to exclude Mick/John from a potential future album/tour.
