I would love to gain insight to how FM fans feel about all of this.
I'll be seeing Joe Jackson in July. So glad it's not an arena show!
From the Fleetwood Mac fan forum, there are several "factions".
The fans that love the Lindsey-era, are obviously very unhappy. To them, the band turned on his "creative leader" and sacked him much like The Clash did when they "fired" Mick Jones.
The fans that love Stevie are generally ok with this as they see this as a chance to focus on her FM songs many of which haven't been played in decades.
The fans that love the pre-Lindsey years (the band had nine albums before Lindsey joined) are also generally happy as this means that they'll finally hear all those great Peter Green/Danny Kirwan/Bob Welch songs in concert.
