Well I have to respectfully disagree with ya Mr. Jones, there is a magic that happens when Jimmy, Robert and John get together with the idea of writing music. Jimmy is quoted as saying he has some good stuff he has worked on that would be a good fit for Zepplin to record and I would love to hear it after Robert and John's input/contribution !!!
The only wildcard is Jason and how he will fit into the mix of things as the 3 have not really recorded with him as of yet, except Jimmy and that was brief as well as a long time ago.
WonderfulOne and City Don't Cry would of been Monster Hits if they would of had JPJ's input and been released on an album as Official Led Zepplin material.
I have nothing but faith in the boyz, they just need to "git er dun"
