A George Lucas amount of Edits...

So I recently bought an original TSRTS live album (from the motion picture) and was shocked. To start, Rock and Roll sounds very different, the mix is way weirder. Other than some odds and ends here and there, the one song that’s WAY different is Dazed and Confused. I’m aware cuts had to be made from the LP (cause the song is 30 minuets long) but you can here mistakes and just way different phrases played here and there. My question posed is which version is right? The 30 minuet masterpiece I’ve heard so many times or the 26 minuet version from the original LP.

Depends what you mean by "right". See the following essential website for all you need to know about the editing on all versions of TSRTS;

Most hardcore Zep fans prefer the original 1976 mix and edits. However, I'd say the truth is more complicated than that.

The current/2007 version has inferior versions of Celebration Day (different guitar solo), No Quarter (2 minutes of amazing soloing cut out), and Whole Lotta Love (Crunge section cut out via a horrid, jarring edit). For the rest of the tracks, though, it's really a matter of taste whether one prefers the 1976 or 2007/2018 versions.

1976 - FTW!

1976 for me. But you really can’t go wrong with the Heywood version
