I don't know if this has been discussed, since I don't follow this forum enough. I just read "All Over Again" (from Time album) was performed on the 2018 tour as a live duet between Christine McVie and Stevie Nicks.
Since the lyric mentions "Well it's it's time to move on to the rain. And finally break the chain", that could be the answer of "Who Expects This Band To Carry On After This Week?".
But then it says "In spite of the heartaches and troubles in love I'd do it all over. Do it all over again"
So...
