Overnight Thread and Distraction

Behold, the earliest known Led Zeppelin recording. Part of a December 1968 show that took place three weeks before the band's Led Zeppelin album came out, this version of "Dazed and Confused" is part of a full-show bootleg that's been available to fans for awhile. This is just its first time on YouTube. Apparently, when this was recorded, Led Zeppelin was so obscure that they were listed as "Len Zefflin" on ads for the show.
