I was thinking that LB has been "fired" previously from the Mac.
Happy Listening!
When Adrian Belew and Fripp were in conflict of breaking up away from King Crimson, I was worried, because I can't imagine King Crimson without any. Not much worries about Fleetwood Mack at all.
I saw Fleetwood before they had Lindsey and Stevie.  They were an opening act at the Fillmore East.  Can't remember who the headliner was.  So many greats - Who, BS&T, Mothers.  
mike campbell is one of my all-time favorite guitarists, and neil finn is a hugely underrecognized songwriter, one of the best of the last decade, so i hope they get to show their own stuff and not merely recycle old fm songs.
@hodu +1, I too thought it was very telling that they needed two guitarist to replace LB.
