Exactly, and even promote a brand new song live before album release. And they've called RfyL tour "big", so a three-year-long jaunt with 103 - 105 shows played combined would be a good example of this one. I think a tour like that and a documentary would be a great PR platform for the 18th album.If any tour is going to be 3 legs it will be this one, I can see them doing a final run across Europe 2027 very easily.
Especially if they are planning a new album, they could record it early 2027, for a Sept / Oct release so it would make sense to fill the year with RFYL Leg 3 in between.
