Led Zeppelin - Bron-Yr-Aur

I'm going to go back to my post here in March about "Bron-Yr-Aur Stomp." The video above is "Bron-Yr-Aur," which was misspelled on the Physical Graffiti album as "Bron-Y-Aur." The studio version appears during the film, The Song Remains the Same. As the video title says it's not the "Stomp" version, which appears on Led Zeppelin III.
