I agree with most of this post. But, the assertion that Plant would have been gone shortly after the scheduled NA 81' tour with Bonham still breathing is not quite that easy to deduce. Without Bonham there, Plant really only had Jimmy and he was busy battling his demons. Don't think he ever cared much for Jones other than his musicianship, and I think the feeling was mutual there. But, if Bonham hadn't died, it wouldn't have been as desirable/easy to just leave Led Zeppelin behind and never look back the way he did, no way, not with Bonzo still in the band.
