Reconstituted RATT And The Issue Of Who Is The Band

It's old news by now that two really key things are happening with RATT.  First, three of the original members - vocalist Stephen Pearcy, guitarist Warren DeMartini, and bassist Juan Croucier - are gearing up to tour (and here's hoping they play Summerfest here in MKE!).  Second, drummer Bobby Blotzer definitively lost his case to use the RATT name in court, and that name has now passed back to those other three original members.

Those two bits of news would be interesting enough on their own accounts - after all who doesn't like the idea of (as much as can be mustered of) classic RATT touring again, and who isn't happy to see the group name reverting back to more of the original members - but there's also a philosophical issue raised by all of this as well.

Who is the "real RATT" in this case?  Pearcy, DeMartini, and Croucier? Or Blotzer?  Both?  Neither?  Or if we think about it more generally - when a band splits up, and multiple members lay claim to the band's name, who should we consider to be the band?
