maybe Lindsey and Christine inisisted they do some BuckVie tunes this time around, so the setlist is not as stale or set in ancient past as it usually is.
we can imagine how that type of demand would not go over well.
frankly though, i don't think they ever even came to discussing setlists, but you never know. we do know Lindsey has been frustrated with GH tours and stale setlists forever and was trying to find
something - anything - to be different from tour to tour. for starters, this year's tour could have had 2 BuckVie songs that were never performed before - Carnival Begins and On With The Show - both songs that are very much about Fleetwood Mac.
