I agree that that is a discussion that should happen. I would argue that are still a band as they have never officially split up. That being said, how long does a band have to be "inactive" before the are a were? If you consider they haven't put any new music out in 15 years, does that count? That being said, even if we determine they "are" a band, Roger Waters and Richard Wright should not be listed as members. (In my opinion only, of course)
