I think too Baby Man, Wild, even the final version of White Ashes would never been on an album as for everything pre 2012
Obviously the fact some of these tracks never appeared even on the huge "Float" collection, makes me leave a small hope.
Maybe there's a track which will be the 13th full moon
Path of fortune
I say this because I've already seen it appearing somewhere as title on https://genius.com/albums/Peter-gabriel/I-o for example. And they usually have released other titles before the official releasing, usually revealed truth.
But there are other stuff I'm wondering about. For example the track about aging he quotes often in the last years:
About your assumption regarding the 13th full moon.
I know this title is being discussed bit has anybody really seen this in one of the videos? I checked this a couple of times and can't find the sequence.
Peter said anyway that there will be a surplus. So I won't be surprised in case he just continues ...
