"Definitive lineup" is a completely vague and subjective criteria. Therein lies the problem with this "institution". As Paul Stanley said, "If the rules don't apply to everybody, then they're not rules".
I agree completely. But what Paul isn't realizing is that it will always be subjective based on the fact that "definitive lineup" is indeed so subjective. It's going to differ from band to band and there can't possibly be any definitive "rules" unless there were such a thing as a "definitive" definitive lineup. That's something that every single band inducted has had to deal with.
Credence Clearwater Revival was a mess too. Fogerty wouldn't even let the other guys on the stage, and they were in the freakin' building.
And look what a fiasco Van Halen was.
Don't forget Blondie! What a meltdown there.
