My Friday night rambles...
Christine feels like the very essence of Fleetwood Mac to me. Where would this band be without her contributions? That instantly recognizable smooth voice, jaunty keys, multiple hit songs. The ying to Stevie's yang. Her countenance and very presence within the band for so long cannot be undervalued in my humble opinion. I realize Mick and John have more years in the band than she, but without her songwriting bridging multiple eras and providing continuity they wouldn't have lasted long after PG's departure.
SYW is practically unlistenable to me. I'm sure her absence is no coincidence as to why.
I am a big LB fan and consider him critically important to their successes, but I cannot deny that Christine is truly the lynchpin of the band. Sure "it's Mick's band" and he's the showman, but he'd have no band without Christine.
