Sun and Steel again... Oh well, I suppose it
is possible...
I just don't see why it, out of all the songs, would suddenly pop up, especially given the amount of setlist candidates that are somewhat similar type of songs and sheer amount of more likely options from Piece of Mind; Flight of Icarus is a single, hence not a deep cut per se, but I would absolutely welcome it for another victory lap. It sounded pretty decent even on the tougher nights of 2019 and I'm quite confident it would still sound great next year.
