the band is as close as ever, what a ridiculous speculation to make! lol emre and mikey probably didn't want to be there or didn't need to be, it's not that deep
Palo Santo is a concept album and it's Olly who came up with that concept so he obviously has the most to say about it, Emre and Mikey still show up for other interviews but it wouldn't make sense for them to come even to the ones that are barely related to their work simply to participate and keep up a certain image of the band - surely they have better things to do with their time than just sit around for the sake of it ✌️
