So now all the mysticism becomes clear and we finally know what they were talking about.

Robert Plant, Jimmy Page, and John Paul Jones explained it all on Letterman last night, on the heels of their (collective) Kennedy Centers Honors award over the weekend.

By the way, following the premiere of the concert film, "Celebration Day" last month, Jimmy page revealed that he has been remastering Zeppelin's discography with a release set for 2013.

Word is that the upcoming box sets will include bonus material, such as studio outtakes and unreleased concert footage.

According to Rolling Stone:

 "It will be coming out, bit by bit," Jimmy Page says with a tantalizing lilt in his voice. The Led Zeppelin guitarist is referring to his current labors in the band's archive, preparing new deluxe editions of each of Zeppelin's studio albums, from 1969's Led Zeppelin to 1979's In Through the Out Door, plus the 1982 post-breakup collection, Coda. Page says the reissues will include "added sonic and visual thrills," and he expects to begin issuing the first albums in the series sometime next year."

By the way, It was 32 years ago today, December 4, 1980, that Robert Plant, John Paul Jones and Jimmy Page announced to the public that they would not re-form Led Zeppelin following the death of John Bonham.

(And none of us have ever gotten over it).
