It seems they've always operated on the edge of disbanding, even from their early days. I agree that there's no Jane's without Perry, but his eccentric nature paired with substances apparently isn't tenable for any extended period of time. I can't speak to whether or not he has a substance abuse issue, but given his history, it wouldn't be surprising.It's sad. Say what you want about Perry, but IMO there is no Jane's without him. I have to give him props - he created an extremely distinct sound both with Jane's and Porno for Pyros (and accomplished huge things with Lollapalooza), and I don't think I would have been into either of those bands nearly as much without his distinct and odd presence. I also think there is a deep connection between all four band members - you could see it in Dave's reaction (like: "why do you have to ruin a good thing?") and even Eric's (which was more like rage that Perry would do this when Eric had FINALLY come back). I can only speculate what's going on with Perry, but I would guess it's not actually anything like dementia, but is truly related to how he is hearing and perceiving the performance. I am sure the tinnitus is real, and he is having trouble keeping track of where he is in songs and actually getting the notes out. Contrary to his wife's nonsense, this really should not be about in-ears, unless they are doing it completely wrong, which is hard to believe for 4 old pros. Note that ear issues (whether tinnitus or wax build up) can exacerbate or cause dementia-like symptoms. Couple that with an unstable personality and some substance(s), and Perry lashed out at the nearest person who was doing just fine. If you watch the longer video of this incident, you can see that prior to it happening, Perry was singing where there should have been a guitar solo. Dave walked over and tapped his shoulder, pointed to himself, and started the solo. In the moment, a confused and disoriented Perry thought that Dave was being a dick, shutting him down and taking over. I sincerely think Dave was trying to help, which jives with his confused look when Perry attacked him. Anyway, just my thoughts on the matter. I think there is love between these guys, and I personally would like to see Perry get his s$it straight, because from what I have heard the band was on fire, and there were shows where Perry was singing well. I think they'd been on tour too long and everything imploded.
I hope we eventually get to hear more new material with the original 4, but I'm not optimistic for that or another tour. Maybe it's best to just let it be.
