I've noticed there are quite a few versions of The Battle Of Evermore that still has not surfaced. The version I have is a bit slower and has more heart and soul kinda, but Plant is not hitting the high notes. This should be proof enough there is still quite a lot of stuff to be released. News is saying medical experts say there is someone alive today that will live to 1,000 years old. If they are a Zeppelin fan, they will have the best luck what is yet to come. Edit: I mean the version I have it not from Studio Magik and much different then the 6 version they have. I think it's even multi-track because the vocals are completely in left channel and full music in right channel. Kinda creepy, muting the right channel and just hear Robert 100%
