At worst this is a finite list, but does anyone know how long the longest known live version of Dazed and Confused ran, and from which date? There are a heck of a lot of bootlegs out there to cull the info from, but I'm trying to track down the mother of all versions. I know this song ran in excess of a half hour during the 1975 tour.
Led Zeppelin's concert in Inglewood, California on March 27, 1975 included the longest version of Dazed and Confused the band ever played. On this particular night, they performed an unfathomable 45 minute long version of a song that lasted just 6 minutes and 28 seconds on their official debut release.
The only known document of this mammoth take on the Jake Holmes classic (contrary to popular belief, Led Zeppelin did not write it) is from an audience recording from reknowned California taper Mike Millard, who used professional equipment hidden in a wheelchair to obtain some of the highest-quality audience recordings of the 70's.
