Been thinking about it long and hard, and I think my controversial opinion is that I'd like to see MP rejoin DT. Not necessarily with the level of influence he had before, but with someone who is still enough of a creative contributor.
I wouldn't.
But you know, I have thought about that too. Let's say there was a hypothetical situation where for whatever reason MM decided to leave, or was asked to leave (let's hope neither ever happens), and they did ask MP to rejoin the band.
Would he have as much creative influence? Would he want to take over all the bootleg/setlist stuff that he did before, and if he would, would they let him? I mean, it would be a really weird situation. On the one hand, MP did basically run the band for 25 years, but on the other, since he left, it's been almost 5 years, and since then, JP has been running things quite differently, so DT is a bit of a different machine now, with more constant setlists, click tracks, pre-recorded backing vocals, etc. And for them to LET MP come back, I don't see him being in a position to say, "How about we just pick up where we left off?" But on the other hand, given his controlling and OCD nature, even if he did get to take care of bootlegs, Ytsejam stuff, etc., would he be able to function in the band without having control over setlists, and other executive decisions that JP makes these days?
