I've never had a conversation about the band without this coming up
It really is crazy how they met and have managed to do this.
Well.. the *hope* for new music could be just as faint as the hope for reconciliation :\
I think someone alreayd mentioned that their manager is Joy's husband, but regardless, it definitely sounds like "internal" is in reference to the two fo them.
If I had to render a guess, and its a total guess, is that maybe John Paul wants to continue touring a ton and recording new music, basically striking while the iron is hot because they're pretty popular these days. Joy just had a kid and maybe she wants to take time off/slow down with touring.
This is my best guess too. "Issues of ambition" can only mean so many things.
