It's a tour for the fans. Hats of to the band for that.
We shall see what they do for Power Trip, as I strongly suspect that Celts could make its way for 2MTM and TNOTB or HBTN (one of those), since they are getting paid a lot of money. If this happens, I think it's good news for those who want to hear The Parchment. I know that Parchment lost to DOTC during internal band setlist voting (I have good sources on this), or even drew with it. But there is a band member who decides which one is to be performed, if there is a draw. So, If they switch out DOTC for 1 or 2 classics during Powertrip, I think Parchment has a chance next year.
Songs other than DOTC are staying put for 2024 IMO. And DOTC is also most likely staying. But, there could be changes.
