The song has been remastered and is included on an upcoming re-release of the album, which will be reissued with a companion disc along with Led Zeppelin's other records. Jimmy Page admits wading through vaults of unreleased material was a major challenge.

Page says, "The material on the companion discs presents a portal to the time of the recording... It is a selection of work in progress with rough mixes, backing tracks, alternate versions, and new material recorded at the time."

Even if you thought you'd heard enough of Led Zeppelin, you can choose to soon hear more. The reissue sets are massive. The reissue of their 1969 self-titled debut features a previously unreleased performance recorded on October 10, 1969 at the Olympia Theatre in Paris. The nine-song set features seven tracks from the album, including an epic 15-minute version of "Dazed And Confused," as well as "Heartbreaker" and "Moby Dick," which would debut on Led Zeppelin II later that month.
