I think the perfect FM scenario would've been if Jeremy Spencer left as he did 2/71 while Peter Green was still in the band. FM chose Christine McVie to replace Spencer on the fly. Not to mention the Boston Tea Party album is released worldwide.
Since Christine had the blues chops with Chicken Shack, and playing with FM for "Mr. Wonderful" , it would've worked! That band would've been a monster.
If parallel universe's exist, this would be one outcome of Fleetwood Mac.
