I've often called Christine McVie the "glue" of the classic Fleetwood Mac sound, as one of the central figures in its transformation from a progressive blues act to a mainstream melodic rock band. Her presence has been missed since her 1998 retirement from the band, on the road and on record. Now it appears that Christine McVie has tired of "retirement" and is to return to the group full-time. Perhaps the one-off performance she did with her fellow bandmates in London in September was just a "warm-up." This will definitely give me incentive to see Fleetwood Mac live if they come around this way with Christine!
